Abstract
Aspects and examples reduce the insertion loss and the noise figure of a filter module, which is configured by capacitive elements such as surface acoustic wave resonators and impedance matched. In one example, the filter module includes a filter having a certain passband and a matching resonator for impedance matching of the filter, the passband of the filter being included in a frequency band ranging between a resonant frequency and an antiresonant frequency of the matching resonator, and a center frequency of the passband of the filter being lower than a center frequency of the band ranging between the resonant frequency and the antiresonant frequency of the matching resonator.
