Abstract
There is provided a dual band receiver receiving frequency signals in different bands, the receiver including: a first down converter converting a first band signal into a first intermediate frequency signal; a second down converter converting a second band signal into a second intermediate frequency signal; a first voltage control oscillator supplying a first oscillation frequency to the first down converter; a second voltage control oscillator supplying a second oscillation frequency to the second down converter; a first filter passing the first intermediate frequency signal within a desired bandwidth; a second filter passing the second intermediate frequency signal within a desired bandwidth; and a clock generator converting the first oscillation frequency of the first voltage control oscillator into sampling frequencies corresponding to integer multiples of first and second oscillation frequencies and supplying the sampling frequencies to first and second AD converters, respectively.
