FET Tuner for Television Receiver

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 construted by a FET and the frequency stability is investigted
