Coaxial Adapters in Demand

BNC Adapters

Inter and intra series coaxial adapters and wave guide-to-coaxial adapters are some of the more common components used in RF, microwave and wireless applications. OEM’s and manufacuturing and engineering test facilities are continually required to provide temporary or permanent connections between the many coaxial and waveguide series in use. This is particularly true today where long established connector series (N, TNC, BNC, 8874, 900, SMA,e tc.,) must be mated with interfaces introduced later (3.5mm, 7/16 DIN, SSMB, SSMC, MCX, 7mm, etc.).

Recognizing this need, Coaxial Components Corp maintains a large inventory of MIDISCO and Microwave Distributors components. Some of the most common and some not so common inter and intra series coaxial and coaxial-to-wave guide adapters are available. We can also supply wave guide transitions in standard and double ridge configurations. If you have a requirement not shown in the catalog or our cross referencing tool, simply request engineering assistance through our website or call 772-287-5000.

The user should bear in mind that for best performance, the usable frequency for a given adapter is established by the operating range of the lower frequency interface on the adapter. As a guideline, a table is provided below to summarize the recommended frequency range of the more common coaxial interfaces. These guidelines represent the range for optimum performance. Most adapters are usable at higher frequencies with limitations.

Coaxicom manufactures standard and precision adapters. Standard adapters are usable to frequencies less than 12 GHz for N and TNC, or up to the recommended frequency range for the other series. Precision adapters use an “X” prefix for the part number and feature stainless steel construction for a more precise interface and an extended frequency range for the N and TNC series. In the case of precision N, TNC or SMAs interfaced with lower frequency series (ie: XBM-SM, XNF-BM etc.), the precise construction and stepped internal transition yields improved performance beyond the normal operating range of the lower frequency series.
