US Returns to Manned Space Flight This Week

Comments off 182 Views0

Tech weeks calls it a “Huge Week Ahead for Spacex and Virgin Orbit.” The industry new outlet says “This week could be the biggest week to date for private spaceflight, with landmark launch attempts coming from both Virgin Orbit and SpaceX. Virgin Orbit is looking to join the elite club of private launch companies that have actually made it to space, with a full flight test of its combined Cosmic Girl and LauncherOne system. Meanwhile, SpaceX is looking to launch its Crew Dragon spacecraft with people on board – achieving a number of milestones, including returning U.S. crew launch capabilities, and human-rating its Falcon 9 rocket. SpaceX passed its first crucial flight readiness review (FRR) on Friday for its first ever crewed astronaut launch, setting it up for a full rehearsal of the mission on Saturday leading up to the actual launch Now it’s set for another FRR with partner NASA on Monday, and then the launch should take place on Wednesday – weather and checkouts permitting. This will definitely be one to watch.”

But The Wall Street Journal is sounding alarms for smaller startup companies entering the space race. “With SpaceX Poised for Takeoff, Small Rocket Startups Fall Behind.  SpaceX and NASA are scheduled to launch the first orbital human spaceflight from U.S. soil since the Space Shuttle Program ended in 2011. But as SpaceX dominates the headlines, a large number of small launch startups are poised to fail.” WSJ’s Liz Ornitz explains.

Perhaps CBS News best captures the sentiment of the county — “It’s tremendously exciting”: NASA astronauts counting down to historic launch aboard SpaceX Crew Dragon this week.  The mission, known as Demonstration Test Flight No. 2 — Demo 2 — will mark the second launch of a SpaceX Crew Dragon and the first with astronauts on board. If no major problems are found, the agency is expected to certify the spacecraft for operational space station crew rotation missions, clearing the way for launch of a three-man, one-woman crew this fall.Longer term, NASA also expects the Commercial Crew Program, under which SpaceX and, eventually, Boeing, will launch private citizens as well as professional astronauts, to open up the high frontier to private sector development, including privately operated space stations.

“This is a new generation, a new era in human spaceflight,” said NASA Administrator Jim Bridenstine. “NASA has long had this idea that we need to build, own and operate hardware to get to space. And in the past that has been true.

Spacex Headquarters

For the engineering and manufacturing team at Coaxial Components Corp, its Florida proximity to the launch makes for perfect viewing of the historic event.  Although traditional gatherings along Florida’s east coast will be limited due to Social Distancing Guidelines, the viewing will be just right from the Coaxicom facility.  “We all feel a personal connection to the launch” says Julian Andrews, Coaxicom’s Chief Operating Officer. “We’re proud to be one of the suppliers of RF components to the Spacex team.”  Coaxicom is an industry leading custom manufacturer of RF microwave components and cable assemblies, but on Wednesday, the Coaxicom staff will join team America as we collectively celebrate the return to space through American innovation and adventure.

 

Look Beyond the “RG” Number to Find the Right Coaxial Cable

Comments off 252 Views0

“RG” means “Radio Guide” and was the original military specification for coax cable back in the thirties. Coaxial Cable RG Numbers are generally just an indicator of size. The actual performance of two different RG6 coax cables can be very different. Most RG numbers refer to cables made with specific diameters. Thicker diameters typically have lower attenuation over long lengths, but also may vary in shielding, jacket type, and dielectric type. The important thing to know is what frequency signals are being transmitted through the cable, and then take an in-depth look at the detail of the cable specifications. Here’s a look at a few of the most commonly used coaxial cables.

 

Coaxial Cable DiagramRG6 Coax Cable
RG6 is one of the most common coax cables. Most of the coax cables used in homes to connect internet and TV are RG6 coax cable. This version of coax is widely used to transmit cable TV signals in homes, CCTV circuits and can transmit high bandwidth making it great as internet cable as well. RG6 coax cable is a cost-effective way to install a CCTV circuitry or set up wireless networks in small offices or apartment buildings.

RG8 Coax Cable
RG8 Coax Cable is a military grade coaxial cable. This wiring is composed of a bare copper wire with a solid low-density polyethylene dielectric and a black PVC jacket. Furthermore, our RG8 coax cable has solid protection due to its single bare copper shield within its interior. This product is capable of operating within temperatures ranging from -40°C and +80°C, allowing the cable to be used in a variety of situations. With its military-grade specifications, as approved through MIL-C-17, RG8 coax cable has a maximum operating voltage of 4,000 volts.

RG11 Coax Cable
RG11 coax cable consists of a tinned copper conductor that is resistant to corrosion and can handle a maximum of 4,000 volts. This conductor is shielded in order to reduce interference and increase durability while retaining the cable’s ability to quickly transfer data. On the outside, the cable is protected by a Type I PVC jacket in order to adhere to the military’s MIL-C-17 specifications. Its jacket is able to protect our RG11 from temperatures ranging from -40°C to 80°C. This coax cable’s military equivalent is M17/6-RG11. RG11 is typically used to transmit various types of data, including radio and video signals. Its durability also allows it to be extremely useful in situations that involve direct burial and harsh weather without risk of abrasion. However, according to MIL-C-17, its Type I PVC jacket is contaminating which means that it may weaken with age.

RG23A Coax Cable
RG23A Coax Cable is a military grade coaxial cable. The internals of this wire are unique due to the fact that it has two separate bare copper conductors. The insulation for these conductors are solid, low-density polyethylene insulation with two cores. There are also two shields as well as a PVC jacket to completely wrap this RG23A Coax Cable together. Rated for -40°C to +80°C and 3,000 maximum volts during operation, this product meets MIL-C-17 specifications.

RG174 Coax Cable
RG174 Coax Cable is 50 ohm coax cable used in a vast array of commercial applications, such as sending data signals in GPS and WAN/LAN networks. With a temperature maximum of 80°C, RG 174 loss cable also features a small, flexible diameter. Click on the links below to learn more about the different features of RG-174 cable.

RG316 Coax Cable
RG316 coax cable can be used in direct burial, radiofrequency and telecommunications applications. Often used for the transmission of radio frequency signals, RG316 cable can also be used in wireless communication, broadcast and military equipment. RG316 coax may also be used for high-frequency interconnections between PCB in telecommunications equipment. RG-316 cable is a good choice for applications like these which require good performance and stability in high-temperature environments and superior phase stability, or for applications in demanding environments or with minimal installation space. RG316 is a high-performance coaxial cable that is in accordance with MIL-DTL-17 specifications. The M17 part associated with coax RG316 is M17/113-RG316.

RG400 Coax Cable
The RG400 is a high temperature coaxial cable is used in a vast array of military and commercial applications. With a high temperature maximum of 200°C, in line with other coax cables like the RG142 Cable. This allows installation in heat sensitive environments. M17/128-RG400 is the military equivalent to the RG400 cable. The testing of the RG400 and other military coax cables are very rigorous and the specifications even more so. The RG 400 manufacturers are required to test attenuation and structural return loss by sweeping 22 different 50-ohm cables over the frequency band for which their use is recommended. The RG400 cable is also used for tactical operations and aerospace technology

Fight the Power with an Attenuator!

No Comments 20968 Views0

All devices require a certain amount of energy, but sometimes you are working with multiple devices that have various power requirements. This can create a difficult situation, unless you have a Coaxicom attenuator!

An attenuator is the opposite of an amplifier; it reduces the power between connections, making low power instruments compatible with its higher powered counter parts.

The reasons are clear why you should make sure you have the proper attenuators in your arsenal of connections and adapters. You never want to run the risk of damaging an instrument by delivering an excessive surge.  Too much power can ruin an entire piece of very expensive hardware. You also don’t always want to buy new often costly cable connections rated for less power.

Bottom line, an attenuator serves as both a long or short term solution and will save money along the way.

Coaxicom attenuators are made in the U.S.A. using top grade materials. By using a quality and reliable attenuator, you can maximize the performance of your equipment without having to stock up on multiple cables and other components.

There are myriad attenuator types to choose from, so make certain you are knowledgeable on the power specs for your instruments. If you need a little help, Coaxicom engineers are available and will collaborate to solve any issue or answer any question.

Additional products include attenuator kits, as well as DC blocks, GPO, flange mount and Type N attenuators. Coaxicom also offers attenuators to 300-watts.

Phase Adjuster Connector

Phase Adjustable SMA Adapters & Connectors

Comments off 1114 Views0

Simple Mechanical Phase Adjustment

These SMA connectors for semi-rigid coaxial cables offer a precise, yet extraordinarily simple means of phase adjustment for microwave instrumentation. Coaxicom phase adjustable connectors incorporate a threaded interconnection of variable length. Turning a phase adjustment nut creates small-incremental changes in cable length and hence phase, up to a maximum of 180 degrees at 18 GHz.

MDC 1089-2

MDC 1089-2 & -3 Phase Adjuster Connector

Coaxicom phase adjustable connectors are available in two standard sizes, MDC 1089-2 for .141″ diameter cable and MDC 1089-3 for .085″ diameter cables. Adapter versions, MDC 189-1 (DC-18GHz) and MDC1089A (DC-4GHz) are also available for in-line applications. For phased array radar, test equipment, ILS & other instrumentation using phase matching techniques, the new connectors substitute the ease of mechanical screw adjustments for laborious cable-trimming. Phase matching may be performed at final production stages, allowing less stringent specifications for equipment components. Once established the proper phase setting for each cable is maintained by a connector locking nut. To compensate for system aging, the locking nut may be released and new phase adjustments made at any time.

Unlike other phase-matching techniques with limited frequency ranges which may hamper performance or require use of more than one model, each broadband Coaxicom phase adjustable connector covers the entire range from DC to 18 GHz. Low VSWR is typical (see chart above). Phase adjustment range in degrees is ten times the frequency in GHz (e.g. 100 degrees at 10 GHz, 180 degrees at 18 GHz).

Environmental Performance

Coaxicom phase adjustable SMA connectors are operational at temperatures from -65 detgrees C to +125 degrees C. They also meet the following sections of MIL-Std-202 for environmental conditions. Vibration: Method 204- Test Condition D.
