- This paper present a fully integrated RF front-end beamformer for 802.11ac system. The principle of beam control is to use the array antenna arrangement circuit to control the phased array antenna; the antenna arrangement structure is to compensate for the distance difference caused by such a constructive interference or destructive wave interference. The circuit includes the low-noise amplifiers, passive phase shifters and high coupling transformer. The proposed study has eight different directions. The simulation result shows that the phased array can achieve a total gain of 17.65 dB and consumes 61.1mW under 0.9 voltage supply. Realized by the TSMC 1P6M 0.18um CMOS process, the area of the chip is 2.37mm*1.84mm.
