Handheld Device Promises To Deliver Inexpensive Diagnostics To Developing World
When most people go to the hospital, the laboratory analysis of various tests is taken for granted. In many developing countries, however, this is not the case, and even the most basic laboratory tests may not be available.
Ultra Low Noise Amplifiers
This white paper provides information on two of Skyworks’ ultra-low noise amplifiers; the SKY67150-396LF and the SKY671513-396LF.
Pushing Software Radio Closer To The Antenna
New technologies offer engineers of SDR (software-defined radio) systems diverse opportunities to perform digital-signal processing much closer to the antenna than ever before. Strategies for doing so include the latest wideband data converters, monolithic receiver chips, compact RF tuners, and remote receiver modules using gigabit serial interfaces. Each approach presents benefits and tradeoffs that must be considered in choosing the optimal solution for a given application.
Properties, Test Methods, And Mounting Of Dielectric Resonators
The most important material properties for a Dielectric Resonator (DR) are its dielectric constant (εr), Unloaded Quality Factor (Qu), and temperature coefficient of the resonant frequency (τf).
