The RF PA, as one of the most essential components in any wireless system, suffers from
inherent nonlinearities. The output of a PA must comply with the linearity requirement …

A new behavioral model for digital predistortion of radio frequency (RF) power amplifiers
(PAs) is proposed in this paper. It is derived from a modified form of the canonical piecewise …

This paper proposes a design approach for a broadband and high-efficiency continuous
inverse Class-F (CCF-1) power amplifier (PA) based on a modified elliptic low-pass filtering …

We present a broadband parallel-combined compact Doherty power amplifier (PA) in a 28-
nm bulk complementary metal–oxide–semiconductor (CMOS) device technology for fifth …

The conventional Doherty power amplifier (DPA) theory is limited to single carrier
operations, leading to a nongeneric structure. This paper presents a new analysis that …

With the ever increasing demands for higher data rate, wider bandwidth is required for
improving the throughput. This trend, however, imposes design challenges for the digital …

Most conventional wideband digital predistortion (DPD) techniques require the use of a very
high-speed analog-to-digital converter (ADC) in the feedback path. This paper proposes a …

In this article, we present a novel technique to build digital predistorters that can linearize
broadband power amplifiers (PAs) using reduced sampling rates. In contrast to conventional …

This paper presents a method for pruning power amplifier (PA) behavioral models and
digital predistorters based on compressed sampling theory. Using this method, the number …

Digital predistortion (DPD) is one of the most effective techniques to mitigate the distortions
caused by power amplifier (PA) nonlinearity and memory effects. As the input signal …
