Abstract :
A Ku-band four-bit MOSFET monolithic microwave integrated-circuit (MMIC) phase shifter using MOSFET switching elements and transmission line is presented. Electromagnetic simulation and a compact circuit were employed to yield an MMIC with a 2.2mm × 1.5mm (3.08 mm2) die size. The measured results exhibit the maximum RMS phase error of about 8 degree and the maximum RMS amplitude error less than 0.5 dB across the frequency band from 11.7 GHz to 12.7 GHz. Typical insertion loss is larger than 11.1 dB and input/output return loss is larger than 11 dB.
