Product details

RP-SMA Jack for RG-405 Semi-Rigid Coax — 18 GHz, 50 Ohm

The 18 GHz maximum frequency is the upper end of the SMA specification — this jack will pass signals from DC through the full microwave band without a resonance dip, provided the cable and termination maintain the 50 Ohm impedance. The threaded coupling locks the pair mechanically, so vibration or cable strain won't unseat the interface.

Kit Contents and Cable Compatibility

The 132103RP ships as a 4-piece kit: one RP-SMA jack body, one centre contact (gold-plated brass), and two PTFE insulators. The cable group is explicitly RG-405 (.085" /.086" semi-rigid) — the insulator bores and contact dimensions are cut for that diameter. Using a different cable gauge will shift the impedance and may not seat the centre conductor properly. The contact and shield both terminate by solder, so you'll need a soldering iron rated for the brass body's thermal mass.

Frequently asked questions

Where can I buy 132103RP and how do I get a price?

Submit a request for quote (RFQ) for current pricing and availability — stock and lead time are confirmed at quote time.

What is the 132103RP connector used for?

The 132103RP is an RP-SMA jack for terminating RG-405 semi-rigid coaxial cable in 50 Ohm RF systems up to 18 GHz. It is used in test equipment, antenna feeds, microwave modules, and any application where the reverse-polarity interface prevents accidental mating with standard SMA connectors.

Does the 132103RP kit include all necessary parts for installation?

You supply the RG-405 cable and solder.

Can 132103RP be used with RG-405 semi-rigid coaxial cable?

Yes, the 132103RP is specified for cable group RG-405 (.085" /.086" semi-rigid). The insulator bores and contact dimensions are cut for that cable diameter.
