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 ...
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 ...
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 ...
Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...
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, ...
Gallium nitride (GaN) RF transistors have traditionally been depletion mode, making them difficult to bias. High frequency enhancement mode transistors, such as the EPC8000 series eGaN FETs from EPC, ...
Guerrilla RF’s GRF5509 high-performance power amplifier paired with Impinj’s advanced RAIN RFID reader chips to enable increased read range and improved readability of RAIN RFID tags GREENSBORO, N.C., ...
