Description

DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION A band pass filter is particularly concerned with a multi-band pass filter. The present invention relates to a prior art having a transmission zero point. A conventional design method of a conventional dual-band (four) wave 11 is to connect two: band-pass choppers operating in the same frequency band, which are two different frequency bands. The filtering of the operation is combined with the characteristics of the dual-frequency passband, but the dual-band pass chopper composed of this architecture occupies twice the area of the normal one-band operation, and has a good frequency for the (four) wave. To select characteristics, three: resonators must be used on the single-money machine, so the whole circuit must use six resonators so that the size of the parts is too large, and too many components are likely to cause the circuit to be too large. In addition, n-devices usually use transmission zeros to reduce interference, suppression and image frequency between systems, and the method of designing transmission zeros is as described in Taiwan Patent Publication No. 1268481 "Multilayer Ceramic Technology Filters and Their Structures. , which discloses a method of generating a plurality of transmission zeros and simultaneously synthesizing filters using a plurality of resonators, which use four resonators to generate four transmission zeros, respectively, although the frequency range of the signal to be suppressed can be 'variable components' Adjusting the frequency position of the transmission zero makes the design more flexible, but the component values of the resonator still need to be designed with the passband frequency range of the filter, and in order to achieve good bandgap attenuation, too many resonators must be used. Passing the zero point will make the overall circuit size of the 1377732 become larger.
