• About MMCX Series

Introduction

MMCX, micro-miniature connectors are designed with a 50Ω characteristic impedance, the working frequency is up to 6 GHz. The reliable snap-on mating design offers “low RF-leakage”. Also, the small dimensions allow you to use the connectors where space requirements are critical.
The major application for MMCX series connectors are PCMCIA cards & other small hand-held communication devices.
