  1. In active section, in order to meet performance of out put power above 10dbm, the power amplifier module of ka - band is fabricated by using hmc283 to achieve the 14db conversion gain. there are five parts that include of waveguide - to - microstrip ? mixer ? filter ? power amplifier and waveguide - to - microstrip. input signal ' s power is 10dbm, after it pass waveguide - to - microstrip, it ' s frequency is escalate from 30ghz to 35ghz

    該組件由五個部分組成：功率為10dbm信號經過波導? ?微帶過渡，然後混頻，濾波將30ghz提高到35ghz濾除不需要的諧波鏡頻以及三階交調信號，為了彌補混頻濾波的變頻損耗，加一級功率放大器，此放大器採用hittle公司hmc283晶元，此上變頻放大組件完成了上變頻?濾波?放大功能。
  2. Third, an active mixer which needs only single - end local oscillator ( lo ) input is presented, which simplifies the rf block design and reduces the impacts of the phase noise of lo

    接著本文提出了一個新型的、只需要單端本振輸入的有源混頻器，簡化了整體電路設計，並降低了本振相噪帶來的影響。
  3. This thesis overall views the historical development, future trend, active devices. sensitivity definitions and configurations of microwave and millimeter mixers, and then discuss several kinds of mixers and mixer diodes

    本文系統地介紹了微波毫米波混頻器的發展概況和今後的發展趨勢、實現混頻器的有源器件及其封裝形式以及利用它們實現混頻的優缺點。
