Original Abstract Submitted
an electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna. the transceiver may include a transmit path, a receive path, and a loopback path that couples the transmit path to the receive path. a passive all-pass filter may be interposed on the loopback path. control circuitry may calibrate i/q mismatch of the wireless circuitry using the all-pass filter to optimize the radio-frequency performance of the wireless circuitry. performing i/q mismatch calibration using the all-pass filter may serve to minimize area consumption in the transceiver, may minimize calibration time, and may allow for calibration over a relatively wide bandwidth.
