Improved Analysis of Carrier Wave Frequency Multiplication of AM Signals
Muhammad Taher Abuelma’attii
Using a more realistic model for the class-C amplifier, an improved analysis of the AM carrier wave frequency multiplication is presented. In addition to the cut-off region, the proposed model incorporates the saturation region. Using this model new closed-form expressions are obtained for the amplitudes of the output products resulting from amplifying an AM signal by a class-C amplifier. In contrast with previously published analysis, these expressions are in terms of the easy to define break-points of the class-C amplifier model.
