  1. 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

    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,毫米波段通常採用超外差機,作為第一級就成為關鍵部件。由於在毫米波段,同段高性能的本振源成本高,技術難度大,採用分諧波技術是解決此問題的有效途徑,只需射率1 / 2 、 1 / 4甚至1 / 8的本振率即可實現
  2. By using irm, heterodyne receiver with good image rejection and mmw - to - if once frequency conversion can be realized, which simplified receiver constitution prominently. the number of local oscillation ( lo ) sources is reduces and electromagnetic compatibility ( emc ) of mmw system is improved. also, the size, weight, power consume and cost of mmw receiver is reduced

    採用毫米波鏡抑制,可在保證鏡抑制性能的前提下,採用1次變機,從而大大簡化構成,減少本振數量,改善毫米波系統電磁兼容性,減小機體積、重量、功耗,並降低成本。
  3. This problem could be resolved by using sub - harmonic mixer ( shm ). instead of using mmw lo, shm using microwave signal with frequency equals 1 / 2 or 1 / 4 of mmw lo frequency, thus the technical difficulty and cost of mmw system is reduced remarkably

    採用亞諧波( sub - harmonicmixer )可將本振率降為基波率的1 / 2或1 / 4 ,從而克服了直採用毫米波本振源帶來的困難,降低了射機的技術難度和系統成本。
  4. Once stored, the signals can be transcribed back into an exact replication of the original signal whenever desired. ultra high speed data acquisition is the main technique in drfm. the most common use of the drfm is for replication of complex, coherent signals usually representing radar return signals

    數字射存儲是現代電子對抗系統中有源雷達干擾機的主要組成部分,用於將到的雷達信號的精確的復制信號返回該雷達系統,以此來淆該系統。
  5. Firstly, the theory basis of if digital receiver is introduced, which includes over - sampling digital mixing receiving scheme and mathematic model with which the scheme is proved correctly. secondly, the numerically controlled oscillator ( nco ) is designed and realized

    首先介紹了中數字機採用的過采樣數字數字方案,然後給出數學模型,從理論上論證了該方案的可行性;二、數控振蕩設計與實現。
