摘要： PURPOSE: An RF(Radio Frequency) switching module is provided to reduce the number of components applied to RF switching for dividing a frequency band signal and transmitting and receiving the divided frequency band signals. CONSTITUTION: A diplexer(501) connects to an antenna(ANT), and separates the first frequency band signal and the second frequency band signal. The first SAW(Surface Acoustic Wave) filter(505) passes the first frequency band signal received from the diplexer(501). A phase converter(504) is operated so that a transmission signal with the first frequency band is not received in the first frequency band signal received from the diplexer(501). The SAW filter(506) passes the second frequency band signal received from the diplexer(501). The first LPF(502) passes the transmission signal with the first frequency band by the first frequency band transmitting unit. The second LPF(503) passes a transmission signal with the second frequency band by the second frequency band transmitting unit. A choke coil(507) blocks an RF signal received through the antenna(ANT).
