This article presents the challenges in designing RF power amplifier efficiency. It briefly describes the use of different amplifiers and techniques to create an effective result. This article ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

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.

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

Anyone who has worked with high-power TV transmitters using IOTs or two-way radio repeaters using the same antenna for transmit and receive know conventional circulators are large and heavy due to the ...
