Abstract :
The design, fabrication and performance of a novel multi-octave five-bit GaAs MMIC phase shifter is described. The topology was specifically selected to minimize process variations on performance. The topology of 22.5° and 11.25° phase shift bits is a sharing Lange coupler. Low peak phase error (PPE) (⩽5 degree for 180°, 90°, 45° phase shift bits, ⩽2.5° for 22.5°, 11.25° phase shift bits), low VSWR (⩽1.7), low insertion loss variations (⩽12.8±0.7 dB) are exhibited over 5 to 20 GHz frequency range. The chip size of the MMIC phase shifter is 4.2 mm×2.98 mm×0.1 mm
