ABSTRACT:
The wide bandwidth transceiver includes a receiver section, a transmitter section, and a local oscillation module. The local oscillation module generates a first and a second local oscillation. The transmitter section converts an outbound baseband signal and/or a low intermediate frequency (IF) signal into a first outbound radio frequency (RF) signal based on the second local oscillation when the wide bandwidth transceiver is in a second wireless standard mode and converts the outbound baseband and/or the low IF signal into a second outbound RF signal based on the first and second local oscillations when the wide bandwidth transceiver is in a first wireless standard mode. The receiver section converts a first inbound RF signal into an inbound low IF signal and/or a baseband signal based on the first and second local oscillations when the wide bandwidth transceiver is in the first wireless standard mode and converts a second inbound RF signal into the inbound low IF signal and/or the baseband signal based on the second local oscillation when the wide bandwidth transceiver is in the second wireless standard mode.
