Abstract :
A Ka-band waveguide double-balanced mixer is described which has low noise and broadband performance. A double sideband noise figure of 5. 9 dB was achieved. The mixer is capable of operation over a frequency- range from 26 to 40 GHz. A unique mixer configuration for achieving double-balanced mixer operation is described. The new mixer configuration simplifies the problems encountered in fabricating a double-balanced waveguide mixer at Ka-band.
