Popis:	Semiconductor tunnel devices can be used as mixers or detectors of microwaves and two examples are given in this paper. First, single-barrier tunnel detector diodes are described and their performance is compared with conventional devices at frequencies up to 35 GHz. Second, the predicted and measured performance of resonant tunnelling diodes as mixers at 94 GHz are discussed. Such mixer diodes can exhibit conversion gain but it is shown that their noise figures are, in general, worse than conventional devices. Some conclusions are drawn regarding the likely applications of both kinds of device.
