ABSTRACT:
A multiple band transceiver (10) uses a fixed frequency oscillator (34) to generate a reference signal in both receive, mode and transmit mode for each frequency band. A dual-band variable oscillator (26) is used to tune signals in receive and transmit mode. The use of the fixed frequency oscillator in both modes and in each band reduces the number of oscillating components, simplifying the circuit and reducing power requirements.
