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 ...

AUSTIN, Texas--(BUSINESS WIRE)-- RF power market leader Freescale Semiconductor (NYS: FSL) today introduced an advanced gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) control ...

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 ...

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 ...

GREENSBORO, N.C.--(BUSINESS WIRE)--Guerrilla RF, Inc. (OTCQX: GUER) today announced that its high-efficiency GRF5509 4-watt power amplifier was selected by Impinj (NASDAQ: PI) for use in their ...

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, ...

RF front ends are advancing through the integration of high-frequency passive networks with increasingly efficient active devices engineered for ultra-wide bandwidths and constrained power envelopes.

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 ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...
