In this paper, a 75 - 95 GHz wideband power amplifier (PA) in 0.13-mum CMOS is implemented to explore the feasibility of low-cost CMOS technology for use in 71 - 76 GHz, 81 - 86 GHz and 92 - 95 GHz fixed point-to-point link bands and the 77-GHz vehicular radar band. The fully-integrated design incorporates the power amplifier, matching networks, and input and output transmission line networks on-chip. The designed amplifier achieves small signal gain of 6.0 dB at 77 GHz, a 3-dB bandwidth of 75 - 95 GHz and delivers a saturated output power of 8.1 dBm.
