Integrated band-pass filter and low-pass filter component

The utility model discloses an integrated band-pass filter and low-pass filter assembly, which is integrated by a band-pass filter and two low-pass filters. The two low-pass filters are an input low-pass filter and an output low-pass filter respectively connected to the input terminal and output terminal of the band-pass filter, and the two low-pass filters and the band-pass filter are in matching connection by the internal transmission lines; the two low-pass filters and the band-pass filter are coaxial filters and are all multistage filters, and the band-pass filter is an elliptical function filter; the input terminal of the input low-pass filter is the common input port, and the output terminal of the low-pass filter is the common export. The utility model has simple structure, simple design circuit, high reliability and small volume weight; and can realize the requirements of wide group band and high harmonic suppression to filters.
