Abstract

This paper presents a BAW-SMR filter using a combined ladder-lattice topology for application in W-CDMA reception front-ends (2.11 - 2.17 GHz). The combined topology allies the advantages of both network types, having very steep responses and high isolation at undesired bands. The design of filter was simulated using a combined 2D EM-acoustical analysis procedure, it presents: 1.6 dB of insertion loss, -10 dB of return loss and isolation higher than -48 dB at TX band (1.92 - 1.98 GHz)
