Abstract:

The theory of hot-carrier mixer diodes is presented, and the relationship between diode characteristics and mixer performance is evaluated. The hot-carrier diode is studied relative to the p-n junction and point contact diodes in this range of frequencies below 3 GHz. The conversion loss and noise figure of a frequency converter using hot-carrier diodes has been studied and evaluated. The report also contains an evaluation of conversion loss for a general nonlinear i-v characteristic. Results are presented for a converter with various image terminations and various degrees of nonlinearity. The cooled diode has also been studied as a circuit element in a frequency converter. The theoretical study presented here describes the benefits to be gained from a cooled hot-carrier mixer. Author
