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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless circuitry with loopback path all-pass filters","description":"An electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna.
