Abstract

The band pass filter of the present invention is suitable to be applied to the framework of a multi-layer ceramic circuit. This filter is a semi-lumped filter which comprises a lumped capacitor and a distributed transmission line. And the resonator used consists of a grounded transmission line node (for equalizing induction) and a great value capacitor. Thus the size of the resonator is far smaller than 1/4 of the operating wavelength and has a characteristic of impact scale. Additionally, the attenuation pole of this band pass filter can be very close to the edge of low frequency side of the pass frequency band, thus can have a suppression effect of the sharpness occurred next to the pass frequency band to make this filter suitable to be used in portable communication devices, compact applications and receiving filters in duplexers.
