MMCX Jack for RF Signal Paths That Can't Tolerate Magnetic Interference
The Amphenol 908-NM22100 is a MicroMate™ series MMCX jack — a female socket designed for board-edge or cutout mounting with surface-mount solder termination. This connector carries a 50 Ohm impedance rating and is specified from DC to 6 GHz, covering common wireless, instrumentation, and telecommunication frequency bands. The entire body is beryllium copper with a gold finish, and it is explicitly listed as non-magnetic, which makes it a candidate for MRI-adjacent equipment, electron microscopy, or any RF assembly where ferrous materials would distort the field.
Snap-On Mating and 500-Cycle Durability
Fastening is snap-on — push to connect, pull to disconnect — which is standard for MMCX interfaces and saves panel space compared to threaded SMA. The rated 500 mating cycles is solid for a test-port or field-replaceable interconnect; the gold-on-gold contact interface (center contact gold-plated, body gold-finished) keeps contact resistance stable across those cycles.
Board Mounting and Termination Details
The shield termination is solder as well — no crimp ferrule here, so the cable attachment happens at the PCB trace, not on a cable end. This is a 1-port jack, so it serves as the board-mounted half of the interconnect; the mating plug is a standard MMCX male with snap-on coupling.
