Claim Text:
1. A diversity receiver comprising: a local oscillation signal generator that generates a plurality of local oscillation signals, each local oscillation signal having a phase different from one another; a first frequency converter that includes a first switching mixer which is controlled to be on or off by at least one of the plurality of local oscillation signals, and that converts a frequency of a first input signal to generate a first output signal by combining the first input signal with the at least one of the plurality of local oscillation signals; a second frequency converter that includes a plurality of logic circuits, each logic circuit delivers a corresponding one of the plurality of local oscillation signals, and a second switching mixer which is controlled to be on or off by an output of the plurality of logic circuits, and that converts a frequency of a second input signal to generate a second output signal by combining the second input signal with at least one of the plurality of local oscillation signals, each output of the plurality of logic circuits being activated or deactivated in accordance with a corresponding one of phase control signals, each phase control signal indicating a phase adjustment amount to the corresponding one of the plurality of local oscillation signals; and a combiner that combines the first output signal and the second output signal.
