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 ...

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 ...

Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...

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 ...

The design and modelling of power amplifiers are central to advancing high-frequency applications, including wireless communication, radar, and satellite systems. In these devices, accurately ...

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, ...

Guerrilla RF’s GRF5509 high-performance power amplifier paired with Impinj’s advanced RAIN RFID reader chips to enable increased read range and improved readability of RAIN RFID tags GREENSBORO, N.C., ...
