Patent ID: 6959175

Claim:
A receiver comprising: a plurality of receiving blocks, each receiving block having an antenna, a frequency mixer that frequency-converts a reception signal received at the antenna, a local oscillator that supplies a local oscillation signal to the frequency mixer, a PLL circuit that sets an oscillation frequency of the local oscillator, and an intermediate-frequency circuit that selects an intermediate-frequency signal out of an output frequency-mixed signal of the frequency mixer; an adder that adds together output signals of the plurality of receiving blocks; a reproduction processor that reproduces an output added signal of the adder; an adjustable reference-signal generator that: supplies phase-shifted reference signals respectively to the PLL circuits of the plurality of receiving blocks, and adjusts a phase shift of the reference signals such that, upon power being first supplied to the receiver, the reference signals are set to an initial phase-shift adjusted state that was stored immediately before turning off power to the receiver previously and, during steady state operation, output signals of the plurality of receiving blocks have the same phase; and a plurality of switches connected between the respective PLL circuits and the adjustable reference-signal generator, switch-on times of the switches controllable such that the reference signals frequency-divided by the respective PLL circuits have the same phase upon power being first supplied to the receiver.
