No impedance-transforming network is needed; the connector is a transparent pass-through in the signal path. The 8 GHz maximum frequency covers the 2.4 GHz and 5 GHz Wi-Fi bands, the 700 MHz to 2.7 GHz cellular range, and ISM bands at 915 MHz and 2.45 GHz. It does not extend into the 10 GHz+ range used by some point-to-point microwave links or satellite downlinks, so confirm your system's highest fundamental frequency before specifying. ## Cable Fit: LMR-400 and the Termination Sequence This jack is listed for LMR-400 cable, a popular low-loss 50 Ohm cable with a solid or stranded centre conductor and a foam polyethylene dielectric. The cable group designation means the connector's inner bore and crimp ferrule are dimensioned for LMR-400's specific jacket diameter and dielectric size.","metaTitle":"Amphenol RF 031-6873 TNC Jack, 50 Ohm, 8 GHz, LMR-400","metaDescription":"Amphenol RF 031-6873 TNC jack, female socket, 50 Ohm impedance, 8 GHz max, for LMR-400 cable.
