Abstract
A narrowband filter tuned at a center frequency. The filter comprises an input terminal, an output terminal, and a plurality of resonators coupled in cascade between the input terminal and the output terminal. Each of the resonators is tuned at a resonant frequency substantially equal to the center frequency. The resonant frequencies of a primary set of the resonators and a secondary set of the resonators are of different orders.
