One very successful trick I use to simulate radiated immunity on the bench is to run an RF generator into an H-field (loop) probe. The best level seems to be +15 to +20 dBm. This will generate an ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

High-power RF amplifiers are used in telecommunications, biomedical, and military systems. With output power levels ranging up to 1 kW, these amplifiers are typically designed to operate near or into ...

Implementation of the 5G radio frequency (RF) standard is increasing rapidly [1]. Over the past four to six quarters, there has been an increased focus on publications and products that have been ...

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 ...
