Spread Spectrum Scene Online

Spread Spectrum Scene Online

RF chips, white papers, FCC, a variety of specialty books on various wireless/ spread spectrum / RF areas, and a wide range of other information.

Spread Spectrum Scene Online is managed by Pegasus Technologies, Inc. A small design house located in East Tennessee. We do custom RF / wireless design work and also offer a variety of Rf modules that can be incorporated into your designs.

Linear Technology - Analog and Interface Solutions

They have unique Interface products that make blending the real world analog and the digital electronics that makes embedded computing possible.

They have Solutions in power management, data conversion, signal conditioning, wireless and circuit and device interface. 

Linear Technology - Analog and Interface Solutions

Some Special Products include - SmartMesh WirelessHART, Signal Chain ┬ÁModule Receivers, Supercapacitor Chargers, Optical Communications and ┬ÁModule LED Drivers.  

Linear Technology Corporation was founded in 1981 as a manufacturer of high performance linear integrated circuits. Linear Technology products  include high performance amplifiers, comparators, voltage references, monolithic filters, linear regulators, DC-DC converters, battery chargers, data converters, communications interface circuits, RF signal conditioning circuits, and many other analog functions.



The DC9022 SmartMesh WirelessHART RF Certified Starter Kit provides all the tools for evaluating SmartMesh network performance for your application needs, including high reliability, ultralow power, scalability and ease of installation. This accelerates device integration and application development.

The DC9018A-C Evaluation/Development Mote Modules feature easy-to-probe signal pins. In addition, the starter kit provides access to both manager and mote software application programming interfaces (APIs) to enable application software development.

Design documentation

Amplifier schematic [55kb] (aka analogue board; contains two amplifiers) and digital board schematic [48kb] as images.

Note -

I found the amplifier designs extremely good as a learning material. Medical instruments after development should undergo a approval process and have high product safety requirements. So above circuits to be used for study only, not for practical applications. When integrating, Medical professionals have to beta test it and after approval used for further tests.

A simulated electrical noise signal source for experimentation is good enough for Degree Projects.
