Abstract
Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and other aspects of spur suppression in millimeter wave receivers. In one aspect a local oscillator (LO) source is coupled to a quadrature generation circuit having a first output for a first LO signal, and a second output for a second LO signal 90 degrees out of phase with the first LO signal. Each output is coupled to an LO driver, and outputs of the LO drivers a coupled at a first power connection to provide spur suppression associated with a phase difference between the first LO signal and the second LO signal. Similar connections are provided at outputs of first and second mixers for spur suppression.
