This paper presents two different methods to reconfigure Bulk Acoustic Wave-Solidly Mounted Resonator (BAW-SMR) filters. The first method proposes the use of RF-MEMS and the second one proposes the addition of capacitors and MOS transistors. This paper shows also the effect of the gate voltage which controls the filter bandwidth with MOS transistors. The first reconfigurable method, is applied to filters for operation in the WLAN 802.11b/g (2.4–2.48 GHz) and W-CDMA (2.11–2.17 GHz) communication standards. Using the second reconfigurable method, the bandwidth is decreased by 30%.
