A new parallel strip line (PSL) coupled resonator filter is developed for RF applications with differential signalling. A theory for the design of such filters is given. The correct measurement techniques of double-ended (differential) filters with single-ended network analyzers using mixed-mode S-parameters are discussed and measurements on a differential comb-line filter are presented.
