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.

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 ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...

As military and commercial communications converge around SDR, networks demand broadband, multi-band, highly linear RF amplification that legacy technologies can no longer ...
