Abstract: Certain aspects of the present disclosure provide methods and apparatus for calibrating a transceiver for wireless communications. One example method generally includes configuring a first oscillating signal as an input signal to at least a portion of a receiver (RX) path, calibrating a residual sideband (RSB) of the receiver path using a second oscillating signal as a local oscillating signal for the receiver path, and calibrating an RSB of a transmitter (TX) path by routing an output of the transmitter path to the receiver path, after calibrating the RSB of the receiver path. Another example method generally includes routing an output of a transmitter path to a receiver path, using a first local oscillating signal for the transmitter path, using a second local oscillating signal for the receiver path, and measuring an output of the receiver path as a local oscillator (LO) leakage for the transmitter path.
