摘要: Phase shifters are key components in phased array systems. A low loss and variations SiGe differential phase shifter for the Ka-band is described. This bidirectional reflection type (RTPS) design employs a novel diagonal configuration coupler it controlled by single voltage node. The measured results show state of art insertion 5±1 dB, tuning range larger than 180 degrees, frequency 26.5 GHz to 32.8 (21%). At 30 GHz, exhibits 4.8 variation ±0.4 more 206 degrees shift range. RTPS was fabricated standard BiCMOS process occupies 0.64 mm2 die area.
