Abstract :
The characteristics of the commercial germanium microwave mixer crystal are reviewed. The conventional theory for these devices is discussed and criticized on the grounds that minority carrier storage phenomena are completely ignored. A model which includes this effect is proposed, and conversion loss calculations which include the effect of spreading resistance are presented for a highly idealized version of this model. Some possible explanations for the dc characteristics and for the success of the conventional fabrication techniques are offered.
