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.

The RF power amplifier stage is usually the final active block of any electronic system that is transmitting RF power. Relatively low power RF signals are amplified to produce a more powerful signal ...

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 ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...
