The RF power amplifier stage is usually the final active block of any electronic system that is transmitting RF power. Relatively low power RF signals are amplified to produce a more powerful signal ...

An RF power amplifier is a device designed to convert a low power radio frequency signal into a higher power radio frequency signal. Moreover, based on several parameters RF power amplifiers are ...

Radio frequency (RF) power amplifiers are all over the place. Some of them can deliver enough RF output power to do biological harm to somebody. Many such amplifiers are solid state, but many others ...

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 ...

RF power amplifiers are going wide and high to meet wider frequency ranges and the need for more bandwidth. Many wireless electronic systems operate over wide frequency ranges and the need for more ...

This article is part of the TechXchange: Gallium Nitride (GaN). NXP rolled out a family of gallium-nitride (GaN)-based RF power amplifiers (PAs) that uniquely leverages top-side cooling to reduce the ...

Digital predistortion (DPD) has emerged as a pivotal technique for enhancing the performance of radio frequency power amplifiers (RF PAs). By pre-adjusting the digital input signal to counteract the ...

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 Guerrilla RF, Inc ...

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, ...
