Abstract
The present invention provides a broadband waveguide mixer, comprising: a waveguide having a substantially v-shaped groove in its inner surface; a broadband antenna coupling in the V-groove; and mixing means for mixing signals received by the broadband antenna. The present invention further provides a high frequency electromagnetic wave receiver comprising the aforesaid broadband waveguide mixer. The broadband waveguide mixer and the high frequency electromagnetic wave receiver have the advantages of broad single mode operating frequency band, lower loss, lower noise, and they can be easily produced and assembled to lower cost.
