Product details

75 Ohm MCX Right-Angle Receptacle for Board-Edge Coaxial Launch

Rated to 6 GHz max with 0.1 dB insertion loss, it covers the full L-band and most S-band signal paths.

Snap-On Coupling and 500-Cycle Duty

The snap-on fastening type gives a positive tactile lock without threads — quick to mate and unmate in the field. The gold-over-beryllium copper centre contact and gold body finish resist corrosion and maintain low contact resistance over those cycles.
