Inter Series Adapters

2.4 MM – 2.9 MM Inter Series Adapters:

Inter series coaxial adapters are some of the more common components used in RF, microwave and wireless applications. OEM’s and manufacturing engineering test facilities are continually required to provide temporary or permanent connections between the man coaxial series in use. This is particularly true today where established connector series (Type N, TNC, BNC, 874, SMA) must be mated with less common or more recently introduced interfaces including 3.5 mm, 2.9 mm, 2.4mm, 7/16, SSMA, SSMB SSMC, MCX, MMCS, and 7 mm.
Recognizing this need, Coaxicom maintains a large inventory of common and not-so-common inter and intra series adapters. Coaxicom’s catalog demonstrates a sampling of available parts, however, please contact with your custom requirements for a prompt response.
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. The recommended frequency range of each connector series is given on the specification sheet within each section. Most adapters are usable at higher frequencies within limitations.
Coaxicom manufactures standard and precision adapters. Where applicable, standard adapters use an “A” suffix in the part number and are usable to frequencies less than 12 GHz for N and TNC, or up to the recommended frequency range for the other series. Most are nickel-plated brass.
Precision adapters feature stainless steel construction for a more precise interface and an extended frequency range for the Type N and TNC series. In the case of precision Type N, TNC or SMA connectors interfaced with lower frequency series, the precise construction and stepped internal transition yields improved performance beyond the normal operating range of the lower frequency series.

• 75 Ohm SMB and SMC components do note mate with the 50 Ohm series
• 50 Ohm and 75 Ohm Type N components do not mate with each other
• 50 Ohm and 75 Ohm BNC mate without restriction
• 50 Ohm and 75 Ohm TNC mate without restriction
• SMA, 3.5 mm and 2.9 mm mate without restriction
