RP-MCX Connectors
Secure reverse-polarity MCX connectors for compact, high-frequency applications
Overview
Amphenol RF’s RP‑MCX connectors combine the compact size of MCX with added safety and regulatory compliance through reverse-polarity construction. Engineered to reduce accidental mating with standard MCX, they offer reliable performance in tight spaces with secure locking. Ideal for professionals managing regulated wireless systems where connector polarity matters.
Offering broad frequency coverage up to 6 GHz (depending on cable), RP‑MCX connectors ensure signal integrity in RF monitoring, test equipment and wireless infrastructure. Their small form factor and reliable snap‑on coupling make them a preferred choice for portable and embedded RF devices.
