摘要:
A system, apparatus and method for providing filtering functionality and impedance transformation within a BAW resonator network are disclosed. In particular, a BAW resonator network is designed to provide bandpass capability and a transformation between its input impedance and output impedance. By effectively integrating impedance matching functionality within the BAW resonator network, discrete impedance matching elements previously required within a system may be removed or reduced in size. As a result, matching networks and their associated component costs, insertion losses, and board size contributions may be reduced. Harmonic termination may be provided within the BAW resonator network or a prematch stage to improve efficiency of a power amplifier.
