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 ...

Recently, several of my clients have been requesting help with pre-compliance testing in the 10 to 50 V/m range, well beyond what the simple TPI or Windfreak RF synthesizers alone can muster. So, I’ve ...

RF power amplifiers are going wide and high to meet wider frequency ranges and the need for more bandwidth. Many wireless electronic systems operate over wide frequency ranges and the need for more ...

The all-new BBA300-CDE “provides a single amplifier that eliminates the need to switch instruments or bands during a test,” according to R&S. A second model, BBA300-DE, operates from 1GHz to 6GHz.

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.

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 ...
