Abstract

This paper presents a highly integrated low temperature co-fired ceramic (LTCC) RF front-end module (FEM) for cellular/GPS/PCS applications. First, a triplexer composed of two diplexers and a GPS SAW filter has been implemented. Measured results of the triplexer are summarized and compared with simulated results. Next, a cellular SAW duplexer has been integrated into the triplexer with a PI network for duplexing functionality. Higher integrated level has been accomplished with compact module size. Finally, a commercial packaged PCS duplexer has been interconnected to the LTCC module on a test board. The overall responses of triple-band RF FEM are described.
