A class-A amplifier is defined as an amplifier that is biased so that the output current flows at all times. Thus, the input signal-drive level to the amplifier is kept small enough to avoid driving ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

GREENSBORO, N.C.--(BUSINESS WIRE)--Guerrilla RF, Inc. (OTCQX: GUER) today announced that its high-efficiency GRF5509 4-watt power amplifier was selected by Impinj (NASDAQ: PI) for use in their ...

This paper describes the design, development, and performance of a low cost, high-efficiency, 1000 Watt RF power amplifier (PA) for 27.12 MHz, operated from a 300VDC supply. The PA is built around a ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

AVX Corporation has expanded its HQ Series MLC surface mount RF power capacitors to include P90 dielectric versions for high power high frequency applications, such as medical and industrial ...

STMicroelectronics is adding a broad range of devices to the STPOWER family of LDMOS transistors, which comprises three different product series optimised for RF power amplifiers (PAs) in a variety of ...
