A 77 GHz Power Amplifier for Low Cost Radar Transmitters in a 55-nm CMOS Technology
2021 IEEE Asia-Pacific Microwave Conference (APMC)(2021)
摘要
A 77 GHz power amplifier (PA) fabricated in a low cost, low power 55-nm CMOS process for mm-wave radar transmitters is presented. The PA design is based on transformer- coupled topology to achieve compact size and high efficiency. The fabricated PA has a 26.5 dB peak gain with 3 dB gain bandwidth of 9 GHz (72-81 GHz). The PA has more than +11 dBm saturated output power (Psat) within the frequency ...
