摘要： 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 step-impedance resonator connected to the input port, a second lumped resonator and a second step-impedance resonator connected to the output port, a coupling capacitor used for the coupling of the first lumped resonator and the first step-impedance resonator to the second lumped resonator and the second step-impedance resonator. 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.
