Mixers are the key components of many microwave and millimeter - wave systems. the super - heterodyne receiver is always applied in modern communication system, mixer becomes the key component as is at the first part of system. but it is more and more difficult to get the choiceness lo source of the same band with the system is working at high frequency especially in the millimeter - wave. sub - harmonic mixer is a good solution to this problem now. in this circuit we need just half 、 quarter 、 even 1 / 8 of the rf signal frequency. in this paper the design and fabricate of sub - harmonic hmic mixers ( 2, 4 ) at w - band are introduced
混頻器是微波通信、射電天文學、雷達、等離子物理、遙控、遙感、電子對抗,以及許多微波測量系統中至關重要的部件。在現代通信系統中,毫米波頻段通常採用超外差接收機,混頻器作為第一級就成為關鍵部件。由於在毫米波頻段,同頻段高性能的本振源成本高,技術難度大,採用分諧波混頻技術是解決此問題的有效途徑,只需射頻頻率1 / 2 、 1 / 4甚至1 / 8的本振頻率即可實現混頻。In order to test the real - time temperature in the cooking cocoon machine, which is favourable to develop the management of the produce, this thesis exploit a system of remote testing, by adopting wireless remote detecting, on the basis of actual thing in the produce locale, which solve the problem that it can ? test the dynamic real - time cooking cocoon temperature
