Patent ID: 6952593

Claim:
A multiple band transceiver that allows for frequency scaling of an input signal while utilizing a reduced number of frequency sources, the transceiver comprising: a first frequency source operative to generate a first oscillating signal; a back-end transmitter mixer, electrically coupled to said first frequency source, operative to receive said first oscillating signal and an unmodulated transmit signal and to generate an Intermediate Frequency (IF) transmit signal; a back-end receiver mixer, electrically coupled to said first frequency source, operative to receive said first oscillating signal and an IF receive signal and to generate an unmodulated receive signal; a second frequency source operative to generate a second oscillating signal, wherein said second oscillating signal can correspond to a first band when said transceiver is operating in a first mode or a second band when said transceiver is operating in a second mode; a front-end transmitter mixer electrically coupled to said second frequency source, operative to receive said second oscillating signal and said IF transmit signal, to produce a Radio Frequency (RF) transmit signal that corresponds to said first band when said transceiver is operating in said first mode and corresponds to said second band when said transceiver is operating in said second mode; and a front-end receiver mixer electrically coupled to the second frequency source, operative to receive said second oscillating signal and an RF receive signal associated with said first band when said transceiver is operating in said first mode and associated with said second band when said transceiver is operating in said second mode, to generate said IF receive signal.
