50 Ohm RP-SMA Bulkhead Jack, DC to 18 GHz
The 132291RP: The gold-plated brass body and PTFE dielectric keep the signal path stable across the full DC-to-18 GHz band. The threaded coupling and front-side nut bulkhead mount secure the connector to a panel before the solder terminations are made — a sequence that prevents torque stress on the solder joints during installation.
What the 18 GHz and 500-Cycle Ratings Mean for Fit
The 18 GHz upper frequency limit covers L-band through Ku-band — most telecom, Wi-Fi, and satellite downlink applications fit comfortably within this window. The 500-cycle mating life, backed by gold-on-gold contact surfaces (gold body finish and gold centre contact plating), means this jack can be reconnected repeatedly in test-set or field-service roles without the contact resistance drift that tin-plated interfaces show after a few dozen cycles.
Mounting and Termination — Bulkhead First, Solder Second
The bulkhead front-side nut secures the jack to a panel before any soldering. The centre contact and shield are both solder-terminated — the through-hole PCB tails align with the board after the nut is torqued.
