Abstract
A filter assembly operating at wider passband with an enhanced reflection coefficient is provided herein. In certain embodiments, the filter assembly comprises a first filter configured to allow signals received via an antenna node to pass at a first passband, the first filter including a plurality of resonators connected in series and parallel arms, the plurality of resonators of the first filter including a first type of resonator configured to broaden the first passband, at least a series resonator nearest to the antenna node or a shunt resonator nearest to the antenna node among the plurality of resonators of the first filter being a second type of resonator configured to improve reflection characteristics at a stopband of the first filter, and a second filter configured to allow the signals received via the antenna node to pass at a second passband using the second type of resonators.
