MULTIMODE COMMUNICATION APPARATUS
First Claim
1. A multimode communication apparatus compatible with a plurality of wireless communication modes, comprising:
- a plurality of communication units which are compatible with the wireless communication modes independently of one another, and each of which includes a transmitter section and a receiver section,wherein at least one of the communication units includes a variable channel band elimination filter which suppresses, in a transmission signal from its own transmitter section, a band corresponding to a frequency band of a reception channel received by a receiver section of another communication unit; and
wherein the variable channel band elimination filter is capable of varying the band to be suppressed in response to a change of the frequency band of the reception channel.

Abstract
In a multimode communication apparatus that uses a plurality of wireless communication modes, interference between communications under different wireless communication modes is suppressed, a good transmission/reception state in each of the wireless communication modes is ensured. A multimode communication apparatus (100) includes transmitter sections (33), (43) and receiver sections (32), (42) and a plurality of communication units (70), (80) each being compatible with the wireless communication modes independently of one another. The communication unit (70) includes a variable channel band elimination filter (34) for suppressing, among transmission signals from its own transmitter section (33), a band corresponding to a frequency band of a reception channel that is being received by the receiver section (42) of the other communication unit (80). The variable channel band elimination filter (34) is capable of varying the band that is to be suppressed, in response to a change of the frequency band of the reception channel.
