PMI Model No. TD-3D8G4D6G-CD-SMF is a high speed threshold detector designed to operate over the 3.8 to 4.6GHz frequency range. It has an external adjustment to vary the threshold level from -20dBm to 0dBm and a typical VSWR of 2.6:1. The unit is supplied with removable SMA(M-In/F-Out) connectors in a housing that measures 0.85" x 0.63" x 0.20".
