Student Projects with Wes Swartz for 2001-2002

Implementation of a transmitter for generating AM and FM RF signals for a laboratory platform illustrating digital modulation principles

http://people.ece.cornell.edu/wes/Projects

The use of a "software" radio built around new digital ICs requires a complemetary transmitter system. A "software" digital transmitter was designed and built last year by Francis Cheong and Frank Lui that can generate AM and FM modulations that are to be demodulated with software receivers designed as a separate project. Final implementation requires some further efforts.

A number of integrated circuits from Analog Devices provide most of the functionality. (See part numbers below.) Prototyping boards with these ICs were used in last year's designs.

Specific tasks:

Learn how to use the digital transmitter.
Design, implement, and test the AM/FM adder circuitry.
Design packaging and fabricate.
Design several modulation schemes for demonstration purposes.
Evaluate performance.
Document.

Parts to consider:

AD6622 65 MSPS, Quad Transmit Signal Processor.
AD9754 14-bit DAC.
AD9854 Digitally-programmable I & Q synthesizer.
AD9850 Digitally-programmable frequency synthesizer and clock generator.
AD9851 Digitally-programmable frequency synthesizer and clock generator. Driver, Program.
AD9852 Digitally-programmable synthesizer.
AD9853 Digital modulator.
AD9856 Quadrature upconverter.
