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 ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

Most modern RF power amplifiers are built from legacy analog circuits. Typically, such circuits are produced in multi-component modules and in costly, low-volume semiconductor processes like Gallium ...

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 ...

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 ...
