ABSTRACT:
In order to provide a high-gain low-distortion low-consumption-current frequency converter circuit employing an FET and an integrated solid-state unit thereof, an FET type having a large K value and a high gain is used in an oscillator section 180 while another FET type having a small K value and a low distortion is used in an amplifier section 182. The K value of the FET is a parameter measured in microamperes per square volt, expressed in the equation
