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, ...

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 ...
