A wireless communication apparatus comprises a local generator for generating a local signal having a frequency equal to the central frequency of the band group; a first down converter for down-converting a wireless signal in each of the bands into an IF signal; a hopping complex filter for removing an image signal in the frequency range of a band to pass therethrough, among down-converted signals, said hopping complex filter having filter characteristics changeable depending on the hopping between the bands; and a second down converter for converting an IF signal of a band which does not contain said central frequency into a baseband signal in a predetermined frequency range about a DC level.
