Abstract

With the development of multimode and multiband mobile phones, the requirements on electrical components with respect to cost, size and electrical performance have further increased. The tightened space restrictions impose a design challenge especially for W-CDMA band VIII SAW duplexers, where electrical performance requirements are already very high due to the rather small duplex distance of 10 MHz and the high relative bandwidth of the pass bands. In this paper we present our new 2.0 Ã— 1.6mm² SAW duplexer for WCDMA band VIII applications. Despite of its small size and low height profile, the duplexer has a superior selectivity and sufficient power durability.
