W2UC: Union College RF Repeater for Amateur Use Union College, Schenectady, NY Department of Electrical Engineering Senior Project Detailed Design Presentation Robin Stevenson Project Advisor: Prof. James Hedrick

Project Goals Design and construct an RF repeater to extend the range of mobile radios in the area surrounding the campus Provide a platform for future student projects involving RF technology

What is a Repeater? Relays transmitted signal from one location to another Extends the range of weak transmitters Can be used to communicate over geographic boundaries Used by: -HAM (Amateur) Radio Operators -Emergency Services Personnel -Commercial Interests (Trucking)

Repeater Block Diagram Duplexer Controller Antenna (Transmits and Receives) Receiver Transmitter Power Supply Control Line Power Line Signal 447.000 MHz 442.000 MHz Transmit only when there is a signal being received

Design Considerations Off the shelf components vs. designed Location Meet FCC Regulations Stability Transmission power Station identification Interference

Requirements Specifications Measurement Devices Output Power – 10W Receiver Sensitivity – 0.1µV at 20dV SINAD Antenna Radiation Pattern Antenna VSWR less than 1.5:1 Duplexer isolation FM Transmit Deviation Spurious and Harmonic Signals Measurement Devices Wattmeter Calibrated signal generator SINAD meter Field Strength Meter Deviation Meter Spectrum Analyzer

Materials Sourcing Power Supply, microcontroller, crystals will be ordered off-the-shelf using IEF Grant Antenna was constructed as part of another student’s summer research Receiver, transmitter, duplexer have been acquired from railroad surplus

Project Timeline Fall Term Winter Term Incorporate duplexer, antenna Develop block diagram Incorporate controls Get Rx, Tx operational Obtain license Choose freqs, submit for coordination Take performance data Finish Design Document Make necessary modifications to Rx, Tx Begin taking initial data Write paper sections

Any Questions?
