Abstract :
This paper presents a BAW-SMR (bulk acoustic wave-solidly mounted resonator) filter in a ladder topology used for the 802.11b/g standard (2.40-2.48 GHz). Also, it shows the effects of the addition of passive elements (L,C) to reconfigure this type of filters. A reduction of 32% to the bandwidth is obtained when adding capacitances and an augmentation of 30% is obtained when adding inductances.
