Fet Tuner for Television Receiver

Abstract

By setting n, normally being two, for the power-law exponent constant of the transfer characteristic of Field Effect Transistors (FETs), the cross modulation distortion characteristic of a high frequency amplifier and the conversion gain of a frequency mixer are obtained and compared with the measured values. At the same time, considering the Integrated Circuit (IC) form of a tuner, a local oscillator is also constructed by a FET and the frequency stability is investigated By applying these results of the theory and experiment in designing a FET tuner, it has been made clear that the electrical performances can be remarkably improved.
