Abstract: Design, fabrication and characterization of a novel 22.5° and 11.25° multi-octave MMIC phase shifter with a sharing Lange coupler is described over 5 to 20GHz band. The topology was specifically selected to minimize process variations on performance. Low peak phase error (≤ 2°), low input/output VSWR(≤ 1.5), low insertion loss variations(≤ (2.6±0.4)dB) are exhibited over 5 to 20GHz frequency range. The chip size of the MMIC phase shifter is 4.2 mm×0.46 mm×0.1 mm.
