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.

Abstract: Various configurations and arrangements of systems and methods for compensating for variations in VCO output frequencies are described. A system in accordance with the disclosure can include an oscillator circuit including an oscillator, a first variable capacitance diode coupled to the oscillator and a second variable capacitance diode coupled to the oscillator. The system further includes a voltage source configured to apply a first voltage to the oscillator circuit to cause the output signal to comprise a selected frequency, the selected frequency being based on a received reference voltage. The system further includes a controller circuit configured to compare an operating voltage of the oscillator to the reference voltage while the first voltage is applied to the oscillator; and apply a second voltage to the oscillator circuit based on the comparison. The second voltage compensates for a difference between the reference voltage and the first voltage.
