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.

Description

technical field [0001] The invention relates to a high-frequency electromagnetic wave receiver, in particular to a broadband waveguide mixer. Background technique [0002] With the development of millimeter wave (30GHz-300GHz) and submillimeter wave (300GHz-3THz) technologies, the above frequencies are very likely to be applied to personal wireless broadband communication and indoor multimedia wireless access technology. In addition, since the atmospheric attenuation and reverse dispersion of the millimeter wave are smaller than that of the infrared ray, the frequency band of the millimeter wave is suitable for transmission and communication under harsh weather conditions (for example, the presence of suspended particulate matter such as smoke and dust), and thus it can also Used as a means of communication in complex environments such as automotive electronics and traffic navigation. Therefore, a broadband mixer with wide bandwidth and low noise and capable of operating in...
