Broadband Phase Modulators In Integrated Fin-Line Technique For Millimetre-Wave Applications

Abstract

Three structures of broadband reflection type phase modulators in unilateral fin-line are presented.The circuits have been analysed assuming ideal transmission line equivalent circuits for the fin-line sections, while the switching element,a pin-diode is represented by a typical equivalent circuit at Ka-band. The measured insertion loss is better than 1.5 dB.
