摘要: Disclosed is a multi-mode/multi-band wireless transceiver. The transceiver includes tunable duplexer including transmission and reception channel filters of which filtering frequencies respectively are controlled by an external element; control portion for controlling the to correspond channels current service band. Thus, use RF SAW filter unnecessary, while it possible support using duplexer. Therefore, number parts volume can be reduced, weaken specification system.
