Author :
Stephan, K.D. ; Perks, G.
Abstract :
Noise-figure measurements of an X-band slot-ring mixer using quasi-optical coupling of LO and RF energy are described. The mixer noise figure varies from 5.5 to 9 dB over the IF band, and extension of this design to millimeter wavelengths should be straight-forward.
