Abstract

In a conventional mixer circuit, in order to have high conversion gain, high input power is needed. For the mixer circuit of the present invention, by incorporating a modified cascode circuit whereby the input stage FET has a higher saturation current than the output stage FET, the same high conversion gain can be achieved. In addition, the present invention mixer circuit requires an input DC power that is considerably less than that needed for the conventional mixer circuit.
