Rated to 18 GHz with a 335 V voltage ceiling, this jack is meant for precision RF signal paths where the cable is formed to a fixed route and the connector is not regularly disconnected. The 50 Ohm impedance and 18 GHz frequency ceiling define the signal path capability — this jack will pass a clean signal through Ku-band without a significant impedance bump at the launch. The 500 mating cycles mean it is not a test-port connector for daily reconnection; it is a semi-permanent install where the cable is formed once and the connector stays mated.","metaTitle":"TE Connectivity 1-2081205-3 SMA Jack, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity KOAXXA SMA jack, 50 Ohm, 18 GHz max, 335 V, gold center contact, for 0.047\" semi-rigid cable.
