ABSTRACT:
A doppler radar transceiver comprising a transceiving module including a reflex circuit having a single transistor which simultaneously acts as both an oscillator and an amplifier. A capacitor and a resistor are provided in the transistor base element bias circuit to reduce the source impedance of the base bias current to said transistor in the doppler signal frequency band without effecting the radar frequency system of the transceiver.
