What You Should Know When Ordering RF Cable Assemblies for a Government / Military Project.

Comments off 23 Views0

Successful manufacturers in the United States understand that when working with either the government or the military there will be a certain amount of product customization required. This is particularly true when it comes to RF coax cable assemblies. To understand why government/military applications for cable assemblies are so specialized, it is important to know that a large percentage of cable assemblies are used for communication. Often it is vital that these assemblies are durable and fully-functional in the harshest conditions. Sometimes to achieve this…all that is needed is a tweak or slight adjustment to a standard assembly, while other applications may demand a high-performance custom design. But in either case, it is a mandate that every cable assembly meets stringent military specifications.

Examples of where Coaxicom cable assemblies are utilized within military communication is; radio, wireless and portable power. Radio is still the military’s lead horse in communication and has been for many years. Wireless allows for quick and reliable data exchange and portable power allows for efficient ways to power up equipment, even in the most remote areas.

5 Things to Know About RF Connectors

Comments off 125 Views0

Guest Author:  Abi Cool


RF connectors also known as radio frequency connectors are simply electrical connectors which are made to function at radio frequencies in the multi-megahertz range. In areas where screening is of high priority RF connectors are extremely valuable. Every home makes use of RF connectors one way or another from products such as antennas, surge connectors, coaxial cables, radios, and enclosures. These connectors

are used in most cases with different test instruments such as oscilloscopes and a host of others. Types of RF connectors are the quick lock types, standard types, audio and video types, high voltage types, blind mate types, thread types, precision types and a few others. However the connector types very common are SMA, BNC, type N, UHF (PL259), reverse polarity TNC (RPTNC) and TNC.

A lot of people don’t know that RF connectors have gender, yes male and female gender. You can identify the gender of the connectors by keeping the following in mind.
(i) The threads are always found inside of the shell. It should also be noted that RF plugs are male.
(ii) The opposite is the case here as threads of the RF jacks are always on the outside of the shell.
(iii) It should also be noted that the shell of the male, that is the plug, usually covers that of the female (jack).
(iv) It is very important to take note of the polarity when mating a male and female plug. For example, the male and female should both be reverse polarity TNC (RPTNC).

It should however be noted that for a standard polarity male plug, there is a center pin that usually sticks out from the middle and threads are found on the inside of the shell of the plug. While the standard polarity female jack plug is the opposite of the male. It receives the pin from the male by use of its socket, which is also in the middle. The outside of the jack shell has threads. However the situation is different as the reverse polarity male plug receives the pin from the female by use of a socket in the middle designed for the purpose. Threads are found on the inside of the shell. In the case of a reverse polarity female jack, a center is found in the middle and threads are found on the outside of a jack shell.

If you think you know a lot about RF connectors, here are 5 things for you to know.

N Female Receptacle for cable assembly

RF coaxial connectors have been used for a very long period of time for the transmitting of radio signals over signal wires so as to process the signals into a visible or an audible medium. The processing commonly used are of two types. The analog signal is either maintained and reproduced or recorded in the original form. Another type of processing employed is the conversion of the analog signal into a digital signal that is either recorded or processed. Minimizing or controlling signal emissions, maintaining signal integrity and decreasing the effect of external influences are the roles, the coaxial contact play.

In order to ensure that external signals are not in any way picked up by the interior conductor which the signals are transmitted from, the coaxial contact system designs provides the much needed shielding. What usually interfere in processing the required RF signal are stray signals that are usually picked. This is mostly in the form of noise. For the signal to be well processed and either translated, reproduced and even stored, there must be proper modeling in the designing of the contact so as to maintain signal integrity. Avoidance of signal loss through attenuation is the most important element of this design. The weakening of digital pulse trains leads to the degradation and alteration of the pulse when talking of peak voltage loss and times of pulse level rise getting much slower, which are mostly measured in decibels. Due to attenuation or the force reduction of RF signals a lot of RF contacts can be effectively used to transmit digital signals.

One of the frequently used ways of wireless data transmission is the modulation of the digital signal into an analog signal. What follows next is the transmission of these signals which are received on a radio frequency transmission. High-bandwidth coaxial contacts are mostly employed in the maintenance of signal integrity before and after transmission, giving room for the conversion of analog signal to digital signal. It should however be noted that the same contact designs that are used in the maintenance of analog signal integrity can also be used for digital, the exception being that the design is adapted the transmitting and receiving lines as made use of in Ethernet digital networks. In systems that are highly reliable, 4 or more contacts are usually housed in these termini, permitting a data transmission rate of more than 1 GB/s.

An effective RF coaxial system is designed to be used in land, air, space and even marine vehicles; this is because it maintains signal integrity at very high bandwidth combined with offering environmental safety of a high-reliability connector package. Due to the very flexible nature of these connectors, designers can easily combine RF power and data in just a single unit.

The primary task of RF connectors mostly used with coaxial contact systems is the maintenance of social integrity irrespective of its external environment, this is done mainly by providing a structure round the contact. The main elements of high-reliability connectors are their capacity of withstanding exposure to corrosion, shock, dirt, vibration, temperature, dust and liquid intrusion. It is highly important for designers of RF electrical systems to count on both electrical and physical elements when making RF interconnect and transmission systems.

Adapters and Connectors

RF “Connector Saver” Can Save You Money

Comments off 253 Views0

Connector Saver.   

Within any connector family there are three adapters you can use. A male-to-male adapter refers to an adapter with two male ends. This is often referred to as a “barrel” adapter. A female-to-female adapter has two female ends; it is often referred to as a “bullet” adapter. An adapter with one male end and one female end is referred to as a “connector saver“.

Why a Money Saver?                                                                                           

Because this type of adapter is often screwed onto an expensive piece of test equipment or component that requires a lot of connect/disconnect cycles. As a result,  if an incident occurs where one of the connectors is damaged, it is far cheaper to  replace the connector saver (adapter) than to repair expensive equipment that it is protecting.

Inter Series Adapters.                                                                                       

Inter series coaxial adapters are some of the more common components used in RF, microwave and telecommunication/wireless, and networking applications. OEM’s and manufacturing and engineering test facilities are continually required to provide temporary or permanent connections between the many coaxial series in use.

Long Established Connector Series.

Today, this is particularly true where long established connector series (N, TNC, BNC, 874, SMA, etc.) must be mated with less common or more recently introduced interfaces.   Examples of these are 3.5 mm, 2.9 mm, 2.4 mm, 7/16, SSMA, SSMB, SSMC, MCX, MMCX, and 7 mm.

The Coaxicom Solution.

Recognizing this need, COAXICOM maintains a large inventory of common and not-so-common inter as well as intra adapters. The user should bear in mind that for best performance, the usable frequency range for a given adapter is established by the operating range of the lower frequency interface on the adapter. Most adapters are usable at higher frequencies within limitations.

2. 50 and 75 ohm Type N do not mate

Project Diana: First Radio Waves Bounce Off The Moon Today

Comments off 338 Views0

The US Army Signal Corps made the first attempt to “touch” another celestial body when on January 10, 1946, it bounced radio waves off the moon and received the reflected signals.

Dubbed “Project Diana” for the Roman moon goddess, the effort led to what is today known as EME (Earth-Moon-Earth) communications.

Project Diana is often noted as the birth of the US space program, as well as that of radar astronomy. The project was the first demonstration that artificially-created signals could penetrate the ionosphere, opening the possibility of radio communications beyond the Earth for space probes and human explorers.

Project Diana also established the practice of naming space projects after Roman gods and goddesses, like Mercury and Apollo.

Project Diana’s first successful echo was detected by John H. DeWitt and his chief scientist E. King Stodola from a lab at Camp Evans, in Wall Township, NJ.

A large transmitter, receiver, and antenna array were constructed at the lab for the project.

The transmitter, a highly modified World War II SCR-271 radar set, provided 3,000 watts at 111.5 MHz in quarter-second pulses, while the “bedspring” dipole array antenna provided 24 dB of gain.

Reflected signals were received about 2.5 seconds later, with the receiver compensating for Doppler modulation of the reflected signal.

Attempts could be made only as the moon passed through the 15-degree-wide beam at moonrise and moonset, as the antenna’s elevation angle was horizontal. About 40 minutes of observation was available on each pass as the moon transited the various lobes of the antenna pattern. (Source:, Suzanne Deffree -January 10, END Network)

2019 a Big Year for Nasa

Coaxicom’s Focus on Space Expanding in 2019

Comments off 3223 Views1


It’s that time of the year when predictably hyperbolic headlines flood our inbox, when analysts dust off their crystal balls and try to prognosticate what is to come. Coaxicom’s focus on NASA’s progression is gearing up in 2019.

In the military space business, there are strong reasons to believe that 2019 could be a pivotal year. The biggest development to watch will be the space reorganization at the Department of Defense. Right now, the odds appear to be stacked against the Trump administration’s plan to establish a Space Force as a separate military service. But politics is notoriously unpredictable.

Aside from the space reorganization, one major question that aerospace executives would like to see answered in 2019 is whether the increased rhetoric about space becoming militarized and contested translates into a different way of doing business.

“Are we going to see a change in behavior on the part of the customer?” asked Robin Lineberger, leader of the global and U.S. aerospace and defense sector at the consulting firm Deloitte.

Space is becoming an important part of the overall defense industry ecosystem, and global tensions could pose a threat to space assets such as satellites. Given these trends, Lineberger noted, DoD must accelerate the development of resilient space systems. The expectation is that 2019 “will be the year when they start to take real action on process to enable alternative, agile and simpler ways to develop capabilities.”

Of course, change does not happen quickly in the Pentagon, so don’t expect “things to be particularly dramatic next year,” Lineberger said. “It takes a while.”

Companies are anticipating military customers will seek a different way to scope and define what they need. All the talk about flexible satellite designs, disaggregated constellations, and launch on demand has not yet materialized into actual programs or shifted the culture of military procurement, said Lineberger. The traditional mindset that is focused on reducing risk and ensuring mission success will not be transformed overnight, but “if we can open that aperture a bit,” it would be a promising sign, he said.

If a Space Force does come to fruition, “it could be a catalyst for re-looking at how we manage our space assets,” he said. However this turns out, the industry would like to see the reorganization settled sooner rather than later. Business does not like uncertainty, even if the establishment of a new military branch for space promises long-term benefits for contractors, such as increased spending on space programs.

A separate space branch could create “windows of opportunity for nontraditional players to get in the market,” Lineberger said. “You start creating a bit of a market shift, a more commercial approach.”

Most companies would prefer to not cope with uncertainty as they weigh investments and other deployments of capital, he added. But regardless of what happens with the new space branch, the Department of Defense has signaled that the management of space is a higher priority than it has been in the past. “And if it’s important, budgets will come with it. That’s a positive,” he said.

How the reorganization is implemented will have intended and unintended consequences, he said. “Some companies are positioned better than others to travel through that journey.”

In its year-end email, investment bank Morgan Stanley reminded clients that the Space Force debate and the growing space economy are powerful forces driving the market. “We expect industry and technological milestones and capital formation will up the ante starting in 2019.”

On the civilian space side, Boeing and SpaceX could make history in 2019 if they pull off their orbital flight tests for NASA’s Commercial Crew Program.

In other expected commercial developments, Virgin Orbit plans to reach orbit in early 2019 and Blue Origin said it will fly a crewed mission in 2019.

STUART –   After 55 years in the precision RF connector business, North Palm Beach’s David Leiman announced the sale of Coaxial Components Corp and its affiliated companies to the New Owners of Coaxicom on Friday, December 7th. The sale of the privately held global manufacturer based in Martin County completed the transition of leadership to Managing Director Julian Andrews, who has been with the firm since 1989 and has been overseeing daily operations for the past 8 years.

New owners, Laurie Andrews of Jensen Beach and Donna Haas of Stuart, announced the acquisition of the firm, which also included the assets of three additional affiliated companies previously based in New York and Florida. As a result of the transaction, Leiman resigned from his position of President, ending a prestigious career of nearly 60 years. Leiman, who has been recognized as an industry icon, was pleased to see the company’s legacy continue to evolve as a woman-owned entity. The company offers one of the largest inventories of military grade electronic components due to the merge of Coaxicom, Dal-Tech Devices, Microwave Distributors Company and MIDISCO.

“The demand is high for quality US manufacturing in this competitive industry that has been inundated with low-quality imports over the past decade,” says Andrews.  “The focus on American-made quality has been a top priority for supply chain managers and many of today’s top defense industry contractors.” Andrews previously served as the Director of Operations for Coaxicom.

As CFO Donnas Haas of Haas Tech Capital will bring new financial leadership to the company which has generated revenues in excess of $20 million.  Haas will implement an innovative growth plan, designed to take advantage of the strong manufacturing outlook, while developing new markets for the industry-leading Coaxicom and MIDISCO brands.  Under Haas’ stewardship, Coaxial Components Corp will reposition its sales strategy to focus on capturing greater market share of the rising demand for quick delivery, US-manufactured product lines. “I look forward to working with the team to continue to expand Coaxicom’s global position,” says Haas.
