A Transistor TV Tuner with a 4.5 DB Noise Figure

This paper discusses an experimental MADT transistor designed for TV RF amplifier applications and a prototype tuner designed to use this transistor. All of the best techniques available at the present ``state-of-the-art´´ have been utilized in the construction of these experimental units. The last few years have seen a marked reduction in the noise figure, and a marked improvement in the gain, of transistors designed for TV tuner use. The experimental unit to be discussed here represents one new step in the evolution of such devices.
