A transmit/receive element having a transmit/receive circuit that includes a variable frequency transmit phase lock loop and a variable frequency receive phase lock loop, and an output amplifier that receives a modulated transmit signal from the transmit phase lock loop for driving an antenna element. The transmit phase lock loop receives a feedback signal which is (a) the modulated transmit signal during receive intervals and (b) the output of the output amplifier during transmit intervals, such that the transmit phase lock loop is controlled by a feedback signal at all times.
