ABSTRACT:
A communication apparatus associated with a system that uses two or more discontinuous frequency bands. The communication apparatus includes a BPF (band pass filter) including a plurality of BPFs associated with signals having respective frequency bands; a controller that controls each unit to transmit/receive the signals having the respective frequency bands; a down-converter that down-converts a filtered signal into a baseband signal while switching frequencies under control of the controller; a receiver that performs predetermined reception processing under control of the controller; and a transmitter that performs predetermined transmission processing under control of the controller, and common hardware is used in communication in all frequency bands with respect to processing of the baseband signal.
