Abstract: A transmitter circuit with a passive mixer network includes a first outbound signal path configured to carry a first outbound signal. The transmitter circuit includes a second outbound signal path configured to carry a second outbound signal. The transmitter circuit includes N passive mixers coupled to the first and second outbound signal paths and configured to up-convert the first and second outbound signals from a first frequency to a second frequency based on a clock cycle, where N is a positive even integer. The first and second outbound signals are passed through the N passive mixers during each phase of 2*N phases in the clock cycle. The transmitter circuit also includes N radio frequency signal paths coupled to an output of respective ones of the N passive mixers and configured to receive the first and second outbound signals in the second frequency during each phase of the clock cycle.
