摘要：
A 24-GHz bi-directional CMOS reflection-type phase shifter (RTPS) with full 360 degrees phase tuning range and minimal insertion-loss variation is presented. Two circuit enhancement techniques are employed: the broadside-coupled transformer-based hybrid and the pi-type resonated varactor load. The implemented 0.18-mu m CMOS RTPS demonstrates a measured phase shift range of 360 degrees with small insertion-loss variation of +/-1.2 dB at 24 GHz. The chip is 0.33 mm(2) in area and it consumes zero DC power.
