This study presents the design of Acoustic-Wave-Lumped-Element Resonator (AWLR)-based filters using the classical cascade synthesis approach as a simpler and more practical method instead of the coupling matrix (CM)-based synthesis approach. The classical cascade synthesis approach is used to design hybrid bandpass (BP), bandstop (BS), linear phase filters, and BP-BS diplexers using commercially available identical SAW resonators leading to bandwidths wider than allAW filters with higher Q-factors. It is shown that simple circuit transformations enable the quick design of such hybrid filters.
