The nickel-plated brass body and gold-plated brass center contact handle the RF path, while the PTFE dielectric keeps insertion loss to 0.2 dB across the band. This plug is specced for the AT&T 735, 735A, and Belden 735A1 cable group. ## RF Performance and Operating Range Rated 50 Ohm impedance with a 4 GHz maximum frequency and 0.2 dB insertion loss, this is a solid performer for standard BNC duty — test equipment, instrumentation, and low-power RF signal paths. Every amp through the contact makes heat, but at these signal levels the derating is academic.","metaTitle":"Amphenol RF 031-325 BNC Plug, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 031-325 BNC plug, male pin, 50 Ohm, 4 GHz max, 0.2 dB insertion loss.
