QMA Connectors

TE Connectivity's QMA Connectors offer high quality and performance without requiring coupling nut torque. These connectors integrate a snap-on feature into the design, achieving denser packaging and reducing overall applied cost. The QMA connectors provide faster connection and disconnection than threaded SMA connectors and deliver excellent RF performance, supporting frequency ranges up to 18GHz. These connectors offer an IP67-rated version and are fully RoHS-compliant. Typical applications include telecom, routers, networking equipment, test and measurement, wireless base stations, and antennas.
