Abstract
To enable beamsteering capabilities for millimeter-wave radar and communication systems, phase shifters are key components. In this paper a WR3-band (220–325 GHz) phase shifter MMIC is presented, which is based on reflective-type phase shifters and enhanced with an integrated variable gain amplifier for loss-compensation, RMS error optimization and antenna tapering. The circuit has an average loss of only 1.6 dB and a 3 dB bandwidth ranging from 218 to 268 GHz. In this frequency range the maximum phase shift is 247° with phase and amplitude RMS errors below 10.4° and 1.5 dB, respectively. The MMIC was processed in a 50 nm InGaAs metamorphic HEMT technology and has a chip size of only 0.75 × 0.75 mm2.
