The shield termination is solder, and the center contact also terminates via solder. The board-edge launch geometry keeps the signal path short and the impedance transition clean up to 2.6 GHz, provided the PCB trace is designed for 50 Ohm controlled impedance. ## Mating and Field Replacement Mates with any standard MCX plug (male) having a snap-on coupling. The 500-cycle rating means this jack is suited for test points, calibration ports, or any interconnect that sees repeated connect-disconnect cycles in the field.","metaTitle":"Amphenol RF 919-246J-51S MCX Jack, 50 Ohm, 2.6 GHz","metaDescription":"Amphenol RF 919-246J-51S MCX jack, female socket, 50 Ohm impedance, 2.6 GHz max, 500 mating cycles, -65°C to 165°C.
