Abstract
A filter module has a first terminal, a second terminal, and at least one filter disposed along each signal path extending from the first terminal to the second terminal. The filter can include a plurality of series resonators and a plurality of shunt resonators disposed between the series resonators and a ground configured to enhance power ruggedness of the filter module. A matching circuit coupled to the filter performs impedance matching of the filter.

(canceled)
A mobile device comprising:
- an antenna configured to receive a radio frequency signal;
- and
- a front end system configured to communicate with the antenna, the front end system including a radio frequency filter device including a first terminal, a second terminal, and a first filter disposed along a signal path extending from the first terminal to the second terminal, the first filter including a first resonator circuit having at least eight acoustic resonators, the first resonator circuit configured to shift a first resonator frequency out of a first target frequency band, such that when the first filter receives radio frequency signals at the first target frequency band, power consumed by the first filter is reduced as a result of shifting of the first resonator frequency.
