RP-SMA Plug Kit for LMR-200 and Belden 7807A
The Amphenol RF 132235RP is an RP-SMA plug kit — a reverse-polarity SMA connector that mates with standard RP-SMA jacks. It is pre-qualified for Belden 7807A and LMR-200 cables, which means the crimp dimensions and dielectric fit are verified for those cable types out of the box. 50 Ohm impedance, 12.4 GHz max frequency.
Cable Prep and Termination Sequence
Termination is a two-step process: the centre contact solders to the cable centre conductor, and the shield crimps through the ferrule.
Mating Cycles and Contact Reliability
That cycle life suits field-serviceable connections — antenna ports, test points, or equipment that gets swapped during maintenance — where the connector sees regular reconnection. The threaded coupling nut provides positive retention under vibration, and the 375 V rating covers the voltage levels typical of RF power amplifiers and radio transceivers.
