Higher linearity passive mixer

A method for transmitting a high frequency signal comprising:

• receiving a pre-distorted low frequency signal;
• converting said pre-distorted low frequency signal to a high frequency signal;
• transmitting said high frequency signal;
• and
• wherein said converting is done by components with a substantially constant overdrive voltage.

A passive mixer comprising:

• a plurality of n-field effect transistors each with a gate, a source, and a drain;
• a plurality of p-field effect transistors each with a gate, a source, and a drain;
• a local oscillator;
• a first DC bias;
• a second DC bias;
• wherein each of said n-field effect transistor gates are connected to said local oscillator and said first DC bias;
• and
• wherein each of said p-field effect transistor gates are connected to said local oscillator and said second DC bias.
