摘要：

This brief presents a millimeter-wave passive reflection-type phase shifter (RTPS) capable of producing a 360x00B0; phase shift range with low insertion loss (IL) in 28x2013;30 GHz range. The circuit consists of a 90x00B0; Lange coupler and two multi-resonance loads where a switched inductor and CMOS varactors are employed. As opposed to previously reported RTPS requiring multiple control voltages, the proposed reflective load requires only one control voltage for the varactors which results in simplicity and reduced dc power consumption of the control blocks. Fabricated in 65 nm CMOC process, this RTPS achieves a measured average insertion loss of 9.5 dB at 29 GHz while consuming zero dc power. The RTPS occupies only 388 $\times $ 615 $\mu \text{m}<^>{2}$ of chip area.
