提出了一种69-79GHz CMOS多端口功率放大器/辐射器,集成了锁相环,实现了+35.7dBm连续波等效全向辐射功率,旨在降低毫米波系统的封装和测试成本。
Low-cost mm-wave silicon integrated signal generation and processing enable many applications, such as silicon-based automotive radars for self-driving cars and wireless communications. Some challenges encountered in commercialization of such systems are the high packaging and testing costs and high sensitivity to antenna parameters, which can diminish the advantage of integrated silicon solutions. On-chip antennas have been proposed as a solution to reduce the packaging costs [1,2]. Link budget analysis of systems (e.g., radar) necessitates high-power (high EIRP) transmitters while system resolution analysis suggests higher frequency of operation for better spatial resolution. The scaling of CMOS transistors facilitates the latter requirement, but, unfortunately, the lower breakdown voltage of the transistors reduces their maximum power handling capabilities at a given radiator impedance. Several approaches have already been
