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 ...

Radio frequency (RF) power amplifiers are all over the place. Some of them can deliver enough RF output power to do biological harm to somebody. Many such amplifiers are solid state, but many others ...

Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made them an attractive option for some applications. The ...

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.

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, ...

If you need an amplifier, [Hans Rosenberg] has some advice. Don’t design your own; grab cheap and tiny RF amplifier modules and put them on a PCB that fits your needs. These are the grandchildren of ...
