Abstract: Aspects of this disclosure relate to active antenna calibration. In some embodiments, a local oscillator signal can be injected into the receive path for misalignment measurement and calibration of the receive path, a transmit signal from a transmit path can be coupled to a receive path, and the transmit path can be calibrated relative to the receive path.
