| 520 | 3 |a"In any frequency-division-multiple-access (FDMA) satellite communications system the control of intermodulation noise must be considered if all signals are amplified by a single nonlinear power amplifier in the satellite transponder. The subject of this report is the use of Fourier-Bessel series expansion models in the prediction of the intermodulation performance of both travelling-wave-tube (TWT) amplifiers and solid state class C, UHF amplifiers. Both theoretical and experimental results are described and compared. It is shown that in the case of the solid state amplifiers a dynamic characteristic measurement technique must be used before reliable predictions can be achieved. A simple intermodulation noise reduction scheme is described for use with high-power-efficiency-class-C solid state amplifiers. It is demonstrated that a signal-to-intermodulation noise power ratio improvement of 10 dB can be achieved with a minimal decrease in prime power efficiency"--Abstract, page 1. |
