    Abstract: This paper presents a 1.5-GHz RF gain-control phase-shifter fabricated in TSMC 0.18-μm CMOS process. The vector-synthesis topology is applied in this work to achieve a wide range phase-shift from 0° - 360° for the processed RF signal. A gain-control buffer amplifier is added immediately after the phasesynthesizer to compensate the signal attenuation. The measured maximum attenuation is -21 dB for each of four attenuators which are the core circuits of the phase-synthesizer. The measured gain-control range of the buffer amplifier is around -16 dB at 1.5 GHz. The power consumption of the chip is 14.4mW under 1.8 V power supply. The chip size is 0.74 × 0.68 mm2.
