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 ...

With operating frequencies exceeding 300MHz, National’s line of monolithic and hybrid current feedback operational amplifiers have become an attractive option for the RF (and IF) design engineer.

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 ...

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, ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

GREENSBORO, N.C.--(BUSINESS WIRE)--Guerrilla RF, Inc. (OTCQX: GUER) today announced that its high-efficiency GRF5509 4-watt power amplifier was selected by Impinj (NASDAQ: PI) for use in their ...
