The Amphenol 132134-11 is a 50 Ohm SMA jack in a through-hole PCB-mount format, rated to 18 GHz. It uses a gold-plated brass body with a PTFE dielectric and a beryllium copper centre contact finished in gold — the same contact material and plating that gives this connector its 500-cycle mating life. The threaded coupling ensures a vibration-resistant connection once torqued, making it a standard fit for RF test boards, microwave instrumentation, and telecom infrastructure where the signal path needs a controlled 50 Ohm impedance up through Ku-band.
What the 50 Ohm and 18 GHz Ratings Tell You
The 18 GHz max frequency means the connector maintains a usable VSWR through the entire Ku-band (12-18 GHz); beyond that, the through-hole launch geometry and the PTFE dielectric start to limit performance. For a board-level SMA jack, 18 GHz is a solid upper bound — most production RF designs stay well below that, but having the headroom means the same footprint works across multiple frequency plans.
Mounting and Termination — What the Board Layout Needs
The single-port jack has no additional mounting posts — the four through-hole legs carry the ground connection and provide the mechanical retention. The threaded body extends above the board, so the enclosure height must clear the coupling nut and any mated cable connector.
