Multilayer band-pass filter of novel resonance structure

The invention discloses a multilayer band-pass filter of a novel resonance structure. The multilayer band-pass filter comprises a surface mounted 50 ohmage input port, a first part parallel resonance cell, a first zero capacity, a second part series resonance cell, a second zero capacity, a third part parallel resonance cell, a third zero capacity, a fourth part series resonance cell, a fourth zero capacity and a surface mounted 50 ohmage output port, which are all realized through a multilayer low temperature co-fired ceramic technology. The multilayer band-pass filter has the advantages of high out-of-band rejection degree, small insertion loss, high reliability, good electrical property, good temperature stability, good batch consistency of electrical property, low cost, miniaturization and volume production, and is applicable to fields and corresponding systems having high requirements on volume, electrical property and temperature stability and reliability, such as communication, digital radar and wireless communication hand-held terminals which are of corresponding microwave frequency band.
