The threaded fastening and flange mounting feature let you secure it to a panel face with the mating half torqued to a repeatable interface — standard practice for test equipment, instrumentation, and microwave assemblies where the connection sees repeated mate-unmate cycles. ## What the 28 GHz and 500 Mating Cycles Mean on the Bench The 28 GHz maximum frequency covers Ku-band and K-band signals with headroom, making it a fit for satellite communications, radar front-ends, and high-speed digital test. ## Mounting and Termination — Panel Fit and Solder Tail The connector mounts through a panel hole with the flange sitting flush against the outside face; the four screw holes in the flange take #4 or M2.5 hardware (not included) to hold the body rigid against the panel. Shield termination is via a screw — a separate ground lug or braid ring clamps to the body, not through a solder tab. The centre contact terminates with a solder cup: strip the coax centre conductor, tin it, and flow solder into the cup. The PTFE dielectric supports the centre pin and keeps the impedance stable through the transition from cable to connector body.","metaTitle":"Hirose HRM(G)-300-468B-1 SMA Jack, 50 Ohm, 28 GHz","metaDescription":"Hirose HRM(G)-300-468B-1 SMA jack, female socket, 50 Ohm impedance, DC to 28 GHz.
