The development, design and construction of a subharmonically pumped mixer at 44 GHz using GaAs Schottky beam lead diodes is discussed. A simplified theory is used to derive a three-port equivalent circuit of the complete mixer which includes effects such as diode parasitics and filter characteristics. Specific design criteria are developed at each of the three mixer signal frequencies, RF, LO and IF, which relate this equivalent circuit to the observed performance. Author
