Doherty CMOS power amplifiers for 5G technology

Currently, there is a large move towards 5G wireless technology beyond the existing, widely used 4G technology due to an increased use of smart devices, and multimedia content. 5G technology is expected to operate at high frequencies between 15 GHz and 100 Ghz opening up a new horizon for spectrum constrained future wireless communications. Designing high efficiency power amplifiers for such high frequencies presents a new challenge. This paper presents different designs of integrated PAs operating at 15–100 GHz for 5G applications.
