A new mixer design for 140-220 GHz
Abstract
A new Schottky-diode mixer is described which has low noise and conversion loss in the 140-220-GHz band. At 170 GHz mixer noise temperatures of 1100-1300 K have been measured, with 6.2-7.2-dB single sideboard conversion loss. The design should be usable up to about 300 GHz with appropriate scaling. The mixer has been successfully used in airborne radiometers on the NASA Convair 990 and C-141 aircraft.
