Abstract

Amplifiers and filters must work together in modern wireless systems. Traditional technology does not allow these two functions to be combined effectively. However, this paper demonstrates that the technology does exist to integrate filters and amplifiers into one small package. This paper demonstrates that two switched-amplifiers and a FBAR filter can be integrated into a small glass metal SO-8 package. The combination provides 23 dB gain over a 100 MHz bandwidth, 35 dB rejection out of band. This is the only integrated FBAR filter with dual amplifier known to the authors to ever be reported.
