In this paper, an extensive review of the most up-to-date papers on microwave Doherty
power amplifiers is presented. The main applications are discussed, together with the …

Modern mobile communication signals require power amplifiers able to maintain very high
efficiency in a wide range of output power levels, which is a major issue for classical power …

A 90-W peak-power 2.14-GHz improved GaN outphasing amplifier with 50.5% average
efficiency for wideband code division multiple access (W-CDMA) signals is presented …

This paper presents an analysis of outphasing class-E power amplifiers (OEPAs), using load-
pull analyses of single class-E PAs. This analysis is subsequently used to rotate and shift …

A high efficiency multi-mode class-E outphasing RF power amplifier (PA) with a passive
combining circuit is presented. The multi-mode PA combines multiple class-E amplifier …

Изобретение относится к теплотехнике и позволяет повысить теплопередающую
способность. Теплопередающее устройство содержит частично заполненный жидким …

An overview of outphasing transmitters is given. Starting from its basic principles, we discuss
its advantages and drawbacks compared to other high-efficiency amplifier configurations …

Doherty Power Amplifier (DPA) is an old and fashionable configuration, introduced by WE
Doherty in 1936 at the Bell Telephone Laboratories (BTL) of Whippany, New Jersey, for the …

Load mismatch in RF high power amplifier leads to efficiency reduction or amplifier failure.
Instead of impedance tuning, in this paper an outphasing architecture with a tunable non …

A bond wire transformer comprises a plurality of primary bond wires coupled in parallel; and
a plurality of secondary bond wires coupled in parallel, each secondary bond wire being …
