Abstract

In this work, the design of the wideband millimeter-wave power amplifier for multiband communication is presented. In order to achieve compact, simple and robust design, a differential cascade transformer-coupled topology is used. The amplifier is implemented in 90 nm low-leakage CMOS technology and achieves 3 dB bandwidth of 8 GHz (from 60 to 68 GHz) and a peak gain of 18 dB. The P O1dB is better than 5 dBm from 58 to 80 GHz, and peak output power is 11.9 dBm with 1 dB flatness from 62 to 77 GHz. The chip consumes an area of 0.25 mm2 including bond pads and DC current of 125 mA from a 2.2 V supply.
