Reaktanzfilter mit OFW-Resonatoren

摘要

A reactance filter, especially mounted in a ladder type network, with surface wave resonators R1-R5 in which omission weighted normal finger converters are used between reflectors, whereby the arrangement and number of active fingers of the interdigital converters for modification of the capacity ratio (static to dynamic capacity) are so designed that a reduction of the filter band width can be obtained.
