It is now easier and faster to specify and integrate EAW systems.

Abstract: In this letter, a 1.7–6.5-GHz reactively matched power amplifier (RMPA) is designed using a 0.2- μ m gallium nitride (GaN) high-electron mobility transistor (HEMT) process. To achieve an ...

Hearing aids work by amplifying sound through a three-part system: the microphone, the amplifier and the speaker.

A symmetrical Doherty power amplifier (PA) with an extended efficiency range is proposed. This paper proves the existence of a class of symmetrical Doherty PAs having efficiency peaks for back-off ...
