Abstract :
Design, fabrication and characterization of a novel multi-octave 90° digital/analogue compatible MMIC phase shifter is described. The topology was specifically selected to minimize process variations on performance. Low peak phase error (⩽5°), low VSWR (⩽1.5), low insertion loss variations (⩽3.0±0.5 dB) and good phase shift linearity with the control voltage of MESFETs´ gates for the analogous state are exhibited over a 5 to 20 GHz frequency range. The chip size is 4.2 mm ×0.56 mm ×0.1 mm
