ABSTRACT:
The disclosed is a downsized and power saving antenna duplexer. The antenna duplexer includes: diplexer; first surface acoustic wave filter to transmit/receive low channel frequency band signals; first phase shift circuit to match the transmission phase with the reception phase of first surface acoustic wave filter; second surface acoustic wave filter to transmit/receive high channel frequency band signals; second phase shift circuit to match the transmission phase with the reception phase of second surface acoustic wave filter. Diplexer, first phase shift circuit and second phase shift circuit are formed in a monolithic structure in package that includes surface acoustic wave filters. The configuration can provide the antenna duplexer with a compact size, a lower current consumption and a highly efficient performance.
