New diodes cut the cost of millimeter-wave mixers
Abstract
The paper describes efforts to develop practical mass-produced millimeter-wave mixers with performance approaching that of the sophisticated but complex research devices. The whiskered diode requires lengthy and prohibitively expensive processes. A surface-oriented diode eliminates the whisker contact and features relatively straightforward design. Fabrication can be microprocessor-controlled, and use of a suspended stripline transmission line eases the design and raises performance. A subharmonic mixer can be used, which leads to suppression of direct video detection and LO noise.
