Product Details
Introduction
This SMA Female Mixed Technology PCB connector is a high performance version which works to maximum frequency of 26.5 GHz. VSWR is good to reach 1.30 Max. This SMA connector has a brass body with gold plating and has a Beryllium Copper Socket. SMA Jack PCB RF connectors are connected to PCB via soldering feet and center contact pin. This Mixed technology version allows to layout signal trace on the surface of PCB, which provides more space or possibility for engineer to finish their PCB integrity design.
