A compatible multi-polarity control signals multi-octave 180/spl deg/ MMIC phase shifter without driver

Abstract

Design, fabrication and characterization of a compatible multi-polarity control signals multi-octave 180/spl deg/ MMIC phase shifter with either digital or analogue control without driver have been demonstrated in this paper. The main electrical parameters of the phase shifter: low peak phase error /spl les/180/spl plusmn/6/spl deg/, low VSWR /spl les/1.7, low insertion loss variations /spl les/3.8/spl plusmn/0.7dB, over their entire operational bandwidth (4-16 GHz) and small size (4.2mm/spl times/0.64mm/spl times/0.1mm) is obtained.
