提出了一种基于双槽天线的250 GHz单片肖特基二极管接收机。所述双槽天线放置在扩展的半球形高电阻硅衬底透镜上。258 GHz时，天线/混频器的DSB转换损耗和噪声温度分别为9.0/spl plusmn/0.3 dB和2000/spl plusmn/100 K。在更高的低电压功率和匹配的帽层下，测量结果预计将提高约2db。单平面双槽天线接收器的尺寸小于0.3/spl倍/1毫米，包括中频滤波器，是迄今为止第一个全单片250 GHz接收器
A 250 GHz monolithic Schottky-diode receiver based on a double-slot antenna is presented. The double-slot antenna is placed on an extended hemispherical high-resistivity silicon substrate lens. The measured DSB conversion loss and noise temperature at 258 GHz are 9.0/spl plusmn/0.3 dB and 2000/spl plusmn/100 K for the antenna/mixer, respectively. The measured results are expected to be about 2 dB better with more LO power and a matching cap layer. The uniplanar double-slot antenna receiver is less than 0.3/spl times/1 mm in size including the IF filter and represents the first fully monolithic 250 GHz receiver to date.<<ETX>>
