James Harvey RF Technologies for Low-Power Wireless Communications


A survey of microwave technology tailored for professionals in wireless communications RF Technologies for Low Power Wireless Communications updates recent developments in wireless communications from a hardware design standpoint and offers specialized coverage of microwave technology with a focus on the low power wireless units required in modern wireless systems. It explores results of recent research that focused on a holistic, integrated approach to the topics of materials, devices, circuits, modulation, and architectures rather than the more traditional approach of research into isolated topical areas. Twelve chapters deal with various fundamental research aspects of low power wireless electronics written by world-class experts in each field. The first chapter offers an overview of wireless architecture and performance, followed by detailed coverage of: Advanced GaAs-based HBT designs InP-based devices and circuits Si/SiGe HBT technology Noise in GaN devices Power amplifier architectures and nonlinearities Planar-oriented components MEMS and micromachined components Resonators, filters, and low-noise oscillators Antennas Transceiver front-end architectures With a clear focus and expert contributors, RF Technologies for Low Power Wireless Communications will be of interest to a wide range of electrical engineering disciplines working in wireless technologies.

Extreme Low Noise Preampifier - Beis

Very low noise was meant to be 1.5 nV/Sqr(Hz) or less. I thought this should be easy as usual ICs like the INA103 provide as low as 1.0 nV/Sqr(Hz) voltage noise. But I was wrong. Why do low-gain amplifiers produce more noise than a high-gain ones? This is for two reasons: The current noise of the input stage and the voltage noise of the feedback resister network.

Low-noise amplifier - Wikipedia

A low-noise amplifier (LNA) is an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio.An amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise. LNAs are designed to minimize that additional noise.
