TRANSVERSE-MODE RESONATOR FILTER

摘要

The invention relates to a transversal-mode resonator filter with reflectors (R1, R3) and input and output transformers (W1, W2) arranged between said reflectors. The impedance of the input and/or output transformers is adjusted by reducing the original active finger overlapping of the normal finger structure. The amount of reduction can vary when the finger overlapping of the transformers is reduced.
