Abstract
Systems and methods for phase alignment among multiple transmitters are described. In some embodiments, a method may include creating a loop between an RF transmitter and an RF receiver; measuring a first DC signal on the I and Q paths of the RF receiver without inserting a DC signal in the I and Q paths of the RF transmitter; measuring a second DC signal on the I and Q paths of the RF receiver while inserting a non-zero DC signal in the I and Q paths of the RF transmitter; and calculating a relative phase difference between the RF transmitter and the RF receiver using the first and second DC signals.
