This work presents the feasibility of a new method to reconfigure Bulk Acoustic Wave-Solidly Mounted Resonator (BAW-SMR) filters by adding capacitors in series with transistors to the shunt resonators and by controlling these transistors with a 2to4 decoder. This method is applied to filters operating in the W-CDMA (2.11-2.17 GHz) communication standard. Experimental results show a tuning range of 14MHz, whereas 12MHz of tuning range was achieved in the simulation.
