Interferometric power amplifiers
Optics Letters, 1989A general method of producing multielement amplifiers having a single output beam is described. The basic building blocks for these are either Michelson interferometers or Mach-Zehnder interferometers modified by the inclusion of gain in at least one arm of the interferometer.

Summary form only given. Computer Aided Engineering tools can be particularly useful for simulating and designing power amplifiers. This presentation outlines some of the simulations that can be carried out and includes a number simulation results. Power amplifier design often can be enhanced by nonlinear simulation, provided that an accurate model is ...

The Doherty power amplifier (DPA) is hereby presented and described starting from the basic idea up to more advanced and state-of-art results and guidelines. The DPA historical aspect is also covered, describing the timeline of its evolution. Moreover, the reasons related to why this architecture, roughly 80 years after its invention, is still on its ...

Power amplifiers in CMOS technology : a contributio to power amplifier theory and techniques
2010In order to meet the demands from the market on cheaper, miniaturized mobile communications devices realization of RF power amplifiers in the mainstream CMOS technology is essential. In general, CMOS Power Amplifiers (PAs) require high voltage to decrease the matching network losses and for high output power whereas the mainstream CMOS technology is ...
