MICRO WAVE FILTER

摘要

The filter has a resonator comprising line patterns on the dielectric substrate. The resonator comprises an input matching circuit (1), one wave circular resonators (2A,2B) facing each other with a slit having certain gap (S) and having stub projection (T), and an output circuit (3). The central frequency is determined by adjusting the lengths of the slit (S) and the stub projection (T). The resonator can have another shapes like rectangluar or elliptic form.
