Abstract
A transceiver circuit is disclosed. The transceiver circuit includes an antenna, a receiver RF chain configured to receive a receiver RF signal from the antenna, a transmitter RF chain configured to transmit a transmitter RF signal to the antenna, and a controller configured to access a CFO (carrier frequency offset) estimate, and to, for each of one or more working frequencies: cause the receiver RF chain to receive a receiver RF signal from the antenna at each working frequency, generate I/Q measurement data based at least in part on the received receiver RF signal and the CFO estimate, store the I/Q measurement data, and cause the transmitter RF chain to transmit a transmitter RF signal to the antenna at each working frequency, where the controller is further configured to cause the transmitter RF chain to transmit the I/Q measurement data for each working frequency to the antenna.
