The white LCP dielectric and gold-plated brass centre contact suit it for repeated signal-path duty within its 30 mating-cycle rating. ## SMT termination and board layout Surface-mount termination with solder shield termination means this connector reflows in a standard SMT line alongside other passive components. The 50 Ohm impedance requires a controlled-impedance trace on the PCB — the launch geometry (trace width, ground plane clearance) must match the connector footprint to keep the signal path clean to 6 GHz. The LCP dielectric handles the -40°C to 90°C operating range without significant dimensional shift.","metaTitle":"A-1JB U.FL (AMC) Jack, 50 Ohm, 6 GHz, SMT, Active","metaDescription":"A-1JB U.FL (AMC) jack, male pin, 50 Ohm impedance, 6 GHz max frequency, SMT, 30 mating cycles, gold-plated center contact.
