MMCX connections any good?
« on: June 02, 2023, 01:24:19 pm »

A friend uses those MMCX connectors as it's best.

Now using them using on digital DAC connections, with cable RG-174 (as relative thick cable), resulted in now connections and PCB turned as connections recovered. The issue is as short cables and and may heavy strength at the sockets.

Then analyzed how the MMCX deals with hot and GND connections:

- hot looks good

- GND is loose within the connector and socket. The ring (red in picture) made the connections

This let me think, that no tailed connections exists as for the GND and MMCX claims up to 6GHz support as up to 500 connection cycles.

What are your experiences or what are an better as SMA/SMB/MCX has a clear GND connection?
