Abstract :
This paper reports an improved W-band self-oscillating mixer employing a resonant tunnelling diode. A conversion loss figure in the region of 25 dB has been obtained from a single device providing direct down-conversion from 87 GHz to 90 MHz. These devices offer the possibility of achieving conversion gain under suitable conditions.
