MMCX Series



Table of contents

  MMCX micro-miniature connectors are designed with a 50 Ohm 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.
