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 ...

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 ...

Single-cell lithium-ion batteries traditionallyhave powered RF (radio-frequency) linearpower amplifiers in cell phones. Althoughthe use of these linear power amplifiers canhelp to meet the ...

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 ...

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, ...
