It handles signals up to 20 GHz, making it a fit for RF test fixtures, microwave modules, and high-frequency interconnect where the launch into the PCB trace must be clean. The threaded fastening ensures a vibration-resistant mate with standard SMA plug cable assemblies. ## What the 20 GHz Ceiling Means for the Layout The 20 GHz max frequency is the connector's usable bandwidth — beyond that, the return loss degrades and the signal launch becomes a mismatch. For a 50 Ohm system, the end launch footprint must be designed with a ground-plane cutout and trace width that matches the centre pin geometry; otherwise the 20 GHz rating is theoretical. The 335 V voltage rating covers most RF power levels, but the limiting factor at high frequency is the dielectric breakdown in the PTFE, not the air gap.","metaTitle":"Samtec SMA-J-P-H-ST-EM1 SMA Jack, 50 Ohm, 20 GHz, End Launch","metaDescription":"Samtec SMA-J-P-H-ST-EM1 SMA jack, female socket, 50 Ohm impedance, 20 GHz max frequency, end launch mount, gold body.
