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 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 ...

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 ...

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
