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.

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, ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...

A wideband RF power amplifier module from Elite RF covers signals from 20 MHz to 6 GHz, delivering a maximum output power of 20 W. Elite RF can also combine these 20-watt amplifiers to create ...

The worldwide introduction of terrestrial DTV and radio systems will lead to a significant number of new transmitters being installed in the coming years. With the recent rise in energy prices, and ...
