This article describes an extremely simple wireless transceiver, comprising of only a low Q VCO and a phase locked loop IC. It is experimentally shown to, simultaneously, transmit an 8-dBm CW interrogation signal, while concurrently demodulating a phase modulated received signal with sensitivity levels of -120 dBm. This makes the performance similar to conventional transceivers, which require complex superheterodyne type architectures and also require a means to provide a high isolation separate the transmit/receive signals (such as a circulator).
