A nonlinear impedance transformer comprising a plurality of scaled L-C sections. The first section has its inductance and capacitance values selected to establish a characteristic impedance approximately equal to the output impedance of the local oscillator. The last section has its inductance and capacitance values selected to establish an output impedance which substantially matches the input impedance of whatever device to which the nonlinear impedance transformer is coupled. The impedance of each section is scaled logarithmically between the values of the input and output impedances. An FET driver can be integrated on the same substrate as integrated versions of the nonlinear impedance transformer. In such a case, the input impedance of the first section is set to the output impedance of the FET, i.e., about 10 ohms.
