RP-MMCX Connectors

Reverse‑polarity MMCX connectors engineered for secure, compact RF interconnects

Overview

Amphenol RF’s RP‑MMCX connectors merge miniature MMCX form factor with reverse-polarity safety to ensure regulatory compliance and prevent unintended mating with standard MMCX. Their robust snap-on coupling and compact size make them ideal for applications where space is limited, yet performance cannot be compromised. These connectors provide reliable connectivity for demanding RF environments.

Designed to support frequencies up to 6 GHz (cable dependent), RP‑MMCX connectors deliver consistent signal integrity with minimal loss. Built for durability, they maintain performance in portable, embedded and test instrumentation setups where repeated coupling cycles are common.
