Abstract: A wireless communication with a receiver subsystem capable of supporting communications operating on two or three distinct frequency bands while incorporating only one or two oscillating devices, respectively. For example, such a subsystem could be integrated in a wireless communication hand-held device configured to operate within three frequency ranges in order to support Cellular, PCS, and GPS services. The receiver subsystem includes a receiver subsystem front end configured to receive first, second, and third receive signals operating under three different frequency bands. The three receive signals are subjected to front-stage filtering, low-noise amplifier, and bandpass filtering in order to remove any unwanted radio frequency components. The first signal is subsequently down-converted into an IF signal by mixing it with a first reference signal generated by a first voltage controlled oscillator (VCO).
