This work presents a new coupler that unleashes an advanced load-modulation architecture, the Load-Modulated Hexagonal-Coupler-based Power Amplifier (LMHA), designed to extend the power back-off (PBO)...
This paper presents a broadband impedance matching technique for RF power amplifiers based on a single quarterwave transmission line (QTL) used with multiple resonance circuits. It is demonstrated how...
This paper presents a new class of load-modulated power amplifiers (PAs), named as the inverse-balun load-modulated power amplifier (IBMA). For the first time, it is discovered that one coupled-line-b...
This paper presents a two-tier, low-complexity linearization framework for fully digital multiple-input multiple-output (MIMO) transmitters that jointly minimizes total radiated power–adjacent channel...
This work investigates receiver linearization in a four-antenna multiple-input multiple-output (MIMO) system operating in the presence of a strong blocker. The received signals are first spatially com...
This work presents a one-step or one-stage over-the-air (OTA) digital predistortion (DPD) method for millimeter-wave phased-array transmitters that inherently accounts for mutual coupling and power am...
This paper presents a novel adaptive impedance compensation technique for broadband linearity enhancement of Doherty power amplifiers. By incorporating a power-related tunable network with varactor-li...
This work presents an analog pre-distortion (APD) linearizer that employs a piecewise linear shape to accurately approximate the nonlinear inverse characteristics of a power amplifier (PA). The APD am...
This article presents a 6-way Gysel power combiner (PC) for high-power applications in rectangular coaxial guide (rectax). Compared to corporate and radial power combiners, the proposed Gysel PC achie...
This paper focuses on the experimental demonstration of multipactor mitigation in functional devices operating in L-Band via coating ultrathin layers of carbon. A 2nd order filter, based on silvered h...
