The 50 Ohm impedance matches the standard for RF signal chains — any mismatch at the connector launch will reflect energy back and increase VSWR, so keep the cable impedance and the PCB trace impedance at 50 Ohm for a clean pass-through.","metaTitle":"Amphenol RF 919-101P-51SX MCX Plug, 50 Ohm, 6 GHz, NRND","metaDescription":"Amphenol RF 919-101P-51SX MCX plug, male pin, 50 Ohm, 6 GHz max, 335 V, snap-on, gold body, RG-174/316 cable group.
