Patent ID: 8364106

Claim:
A multiple band direct conversion radio frequency (RF) transceiver integrated circuit (IC) comprises: a multiple band direct conversion transmitter section including: transmit baseband module coupled to receive an outbound baseband signal and to produce a processed outbound baseband signal; and a multiple frequency band transmission module coupled to convert the processed outbound baseband signal into an outbound RF signal having a first RF carrier frequency within a first frequency band in accordance with a first band local oscillation when in a first mode and coupled to convert the processed outbound baseband signal into an outbound RF signal having a second RF carrier frequency within a second frequency band in accordance with a second band local oscillation when in a second mode; a multiple band direct conversion receiver section including: a multiple frequency band reception module coupled to convert an inbound RF signal having the first RF carrier frequency into an inbound baseband signal in accordance with the first band local oscillation when in the first mode and coupled to convert an inbound RF signal having the second RF carrier frequency into the inbound baseband signal into in accordance with the second band local oscillation when in the second mode; and a receiver baseband module coupled to receive the inbound baseband signal and to produce a processed inbound baseband signal; and a local oscillation generation module coupled to generate the first frequency band local oscillation when in the first mode and coupled to generate the second frequency band local oscillation when in the second mode.
