A 28-GHz CMOS-65 nm Dual Mode Class-J Doherty Power Amplifier With Integrated Class-G Driver and Impedance-Modulated- Quadrature-Transformer Achieving 21% Back-Off Efficiency

In this paper, a CMOS Class-J Doherty power amplifier (PA) integrating a Class-G driver and an Impedance-Modulated-Quadrature-Transformer (IMQT) to enhance back-off efficiency for multimode operations is presented. The Class-J Doherty PA utilizes a second harmonic termination to improve its efficien...
