ABSTRACT:
A transceiver has an RF oscillator stage shared by the receiving and transmitting modes. The RF oscillator has a feedback loop incorporating a SAW delay line. A switching arrangement selectively couples the antenna to the transmission circuit and optionally couples the antenna to the receiving circuit. The RF oscillator stage is isolated from switching perturbations by small capacitors at the input and at the output of the oscillator.
