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 ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

Marki Microwave has expanded its core amplifier product portfolio with three gain block amplifiers that serve as key components for a complete RF subsystem. The ADM-8622PSM, ADM-8625PSM, and ...

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 ...

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 ...

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 ...

Mouser Electronics is stocking a 5G linear RF amplifier from Qorvo. QPA9822 is designed for 32-node mMIMO (massive multiple-input and multiple-output) antenna systems found in wideband 5G NR (new ...
