S&M2327 Research Paper of Special Issue https://doi.org/10.18494/SAM.2020.2825 Published: September 30, 2020 38 GHz All-pass Phase Shifter with Attenuator Using 0.15 µm GaAs Technology for Wireless Sensors [PDF] Si-Da Tang (Received February 9, 2020; Accepted August 21, 2020) Keywords: pHEMT, phase shifter, all pass, hybrid, Ka band
A 38 GHz all-pass phase shifter designed using the pHEMT 0.15 μm GaAs process is presented. The phase shifter consists of two groups of a low-pass filter (LPF) with a 90° phase shift and attenuators. By tuning the bias voltage, the magnitude and phase of the signal are changed. At the end of the circuit, a power combiner is used to obtain a 360° all-pass output signal. The measurement results show that the phase shifter can achieve phase variation with an insertion loss of about 10 dB and an all-pass work function around a center frequency of 38 GHz. The chip area is about 1.12 mm2. The phase shifter is suitable for sensing circuitry.
