Abstract
The transverse-mode resonator filter has reflectors and input and output converters arranged between the reflectors. The impedance of the input converter and/or the output converter is adjusted by reducing the original active finger overlap of the normal finger structure. The impedance can be increased by shortening the converter length of one converter, by reducing the active finger overlap of one converter by omission weighting, or by reducing the active finger overlap of one converter by overlap weighting.
