Filter using multilayer ceramic technology and structure thereof

The present invention discloses a filter using multilayer ceramic technology. The filter comprises an input port, an output port, a first lumped resonator and a first stepped impendence resonator connected to the input port, a second lumped resonator and a second stepped impendence resonator connected to the output port, a coupling capacitor coupling the first lumped resonator and the first stepped impendence resonator connected to the second lumped resonator and the second first stepped impendence resonator connected to the input port. The filter according to the present invention can provide the multi-transmission zeros in the stopband to isolate the adjacent channel and suppress the harmonics, and provide the transmission poles in the passband to have lower insertion loss. In addition, a manufacturing method for the filter using multilayer ceramic technology is also disclosed.
