Abstract:

This report describes an experimental and theoretical study of Hall-effect mixers for use in receiver applications above 10 MHz. Equations were derived for conversion loss, noise figure and intermodulation. It was shown that the performance of a Hall-effect mixer degrades as frequency increases because of dissipation limitations in the Hall element. Thus, above 10 MHz, the conversion loss and noise figure of the Hall-effect mixer are extremely poor when compared with crystal diode mixers. It was also shown that the spurious responses of a Hall-effect mixer are comparable to those in a crystal-diode mixer for equal conversion loss in both devices. These and other considerations lead to the following conclusions 1 The Hall-effect mixer can be made competitive with conventional mixers only if a material can be developed which would provide efficient operation without the need for low-temperature operation. 2 A Hall-effect mixer using existing materials for the Hall plate should not be considered as a preferred circuit for receivers at frequencies above 10 MHz.
