Abstract:

This thesis presents the theory behind the generation of intermodulation products in the final output power amplifier of a VHF transmitter and the calculations necessary to determine the power in a transmitter produced intermodulation product at the front end of a receiver. The resutls are then applied to the analysis of transmitter produced intermodulation interference in colocated VHF sites. An algorithm is developed for accomplishing this analysis and is implemented in the form of a Turbo Pascal program named TIMAP Transmitter Intermodulation Analysis Program which runs on the Zenith Z-100 microcomputer under the MS-DOS operating system. TIMAP provides a systematic and automated analysis tool for electromagnetic compatibility engineers in the field.
