ABSTRACT:
A high-frequency signal receiver includes a variable gain amplifier for amplifying a high frequency signal input thereto, a local oscillator, a mixer for mixing a signal output from the variable gain amplifier and a signal output from the local oscillator, a filter for receiving a signal output from the mixer, a gain controller for outputting a voltage according to the signal output from the mixer; and a weighting circuit for weighting and summing a control voltage and the signal output from the gain controller for controlling the gain of the variable gain amplifier. The high-frequency signal receiver hence creates a small amount of signal error even when the input signal includes a large interference signal adjacent to a desired signal.
