The analysis and design of an RF-input sequential load modulated balanced power
amplifier (SLMBA) are presented in this article. Unlike the existing LMBAs, in this new …

Digital predistortion (DPD) is the linearization technique most often used to cope with the
inherent tradeoff between linearity and efficiency in power amplifiers (PAs). Adaptation is …

This article presents a technique for load-modulated balanced amplifiers (LMBAs) to
achieve a continuum of load modulation (LM) ratio. This has been possible in prior arts …

In this article, we present a novel recurrent neural network (RNN)-based behavioral model to
linearize radio frequency (RF) power amplifiers (PAs) under wideband excitations. Based on …

A novel architecture to extend the bandwidth of the Doherty power amplifier (DPA) is
presented in this article. It is illustrated that two DPA modes at different frequency bands can …

This article presents a novel method to design the multiband Doherty power amplifier (DPA).
It is illustrated that phase periodic matching networks (PPMNs) can be used as multiband …

This article presents the methodology for designing triple-mode Doherty power amplifier
(DPA) with multi-band operation and extended high efficiency range. It is illustrated that …

Segmenting a silicon modulator can substantially increase its electro-optic bandwidth
without sacrificing modulation efficiency. We demonstrate a segmented silicon IQ modulator …

The future intelligent transmitter will dynamically adjust the transmission configuration on
demand, which will bring new challenges to digital predistortion (DPD). In this article, we …
