QC-SMA™ Quick Connect SMA Plugs feature a push / pull coupling mechanism that is fast and easy to use. QC-SMA™ Plugs are a great alternative to threaded SMA connectors in testing applications because technicians can quickly mate and un-mate these connectors without the use of torque wrenches. Electrical performance for QC-SMA™ Plugs is comparable to standard SMA connectors up to 18 GHz, depending upon the cable type. QC-SMA™ Plugs mate to any SMA Jack with a .200” thread length and, once mated, they can be rotated 360 degrees.
