Modern wireless systems often support multi-standards with spectrum-efficient modulation schemes such as 64QAM and 256QAM and high data-rates. This poses stringent requirements on RF Power Amplifiers (PAs) for their carrier bandwidth, linearity, modulation rate, and efficiency. Several multiband Analog PAs (APAs) and Digital PAs (DPAs) are recently reported. However, multiband APAs often suffer from...
This paper presents a highly linear dual-band mixed-mode polar power amplifier (PA) fully integrated in a standard 65 nm bulk CMOS process. An ultra-compact single-transformer-based passive network provides optimum load impedance transformations simultaneously at two operating frequencies, parallel power combining, and even-harmonic rejection without any tuning elements or band selection switches...
