Abstract : The purpose of the report is to show a technique for reducing the noise output of RF broad band power amplifiers. The report will describe the design, construction, and comparative testing of two types of transmitting systems: (1) a standard crystal oscillator and high gain power amplifier; and (2) a high power voltage control led oscillator and low gain power amplifier phase lock system. Noise outputs over the frequency range of 30 to 75 MHz will be compared on a theoretical as well as empirical basis. These results will serve to show the present state-of-the-art in RF power amplifier low noise design. (Author)
