I have 2 pieces that are brand New and 2 pieces that we soldered wires to test. The units all work perfect. Used are $95.00 each. see my other listing if these will work for you. Microsemi Transceiver MO9062 Full datasheet included in pictures. RF Transceiver K-BAND TRANSCEIVER Microsemi?s waveguide output transceivers are a reliable source of microwave power for speed and motion detection applications. The transceivers are a fully integrated module, with a Gunn diode mounted in the cavity for the transmitter and one or two Schottky barrier diodes in the receiver. An IF output is generated whose frequency is proportional to the target?s velocity. With the two-mixer design, the direction-of-motion is obtained as a phase difference between the two IF outputs.
