This paper presents a 35 GHz continuous tunable phase shifter for phase array system. Composite right/left hand (CRLH) T-line has been utilized for designing the phase shifter, which was fabricated in 65 nm CMOS technology with an area of 0.42 x0.39 mm2. (0.04 mm2. for CRLH core) excluding pads. The measured results show that at 35 GHz it achieves a 0.7 dB average gain and maximum gain variation less than 3 dB. The DC power consumption is 9.4 mW at 1.2 V supply voltage with input P1dB reaching-5 dBm. The phase shifting range is more than 110 with a linear tuning in RH region and LH region respectively at 35 GHz, which can be utilized with a quadrupler together at LO side to realize the whole phase tuning range of 360 at 140 GHz.
