This paper presents the design of a novel antenna duplexer based on a mixed ladder lattice topology using advanced Solidly Mounted Resonator–Bulk Acoustic Wave (SMR–BAW) and Integrated Passive Device (IPD) technologies. The duplexer is designed for application on W-CDMA handsets (Tx: 1920–1980 MHz, Rx: 2110–2170 MHz). The design methodology and implementation issues are discussed. A combined electromagnetic acoustic analysis results in a maximum insertion loss of 1.75 and 2.3 dB for Tx and Rx paths. The Tx–Rx isolation is better than 47/57 dB. The assembly of both Rx and Tx filters on the IPD will be discussed, as well as the simulated and measurement results.
