  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. Active staggered band - pass filter

    有源參差帶通濾波器設計
  3. In this paper they study a position - detecting system based on microprocessor and psd ( position sensitive detector ). the method is as follows : when the ac - signal from psd which is illuminated by modulated light source passes through an active band - pass analog filter, it filters the ac signal which represents the object light source. then the dc - converter circuit transforms it into dc - signal which is used to calculate the position

    這一系統採用的方法是通過對位置敏感探測器psd受到調制目標光源照射后輸出的模擬交流信號進行有源帶通濾波，提取出代表目標光源的調制頻率成份，再將該信號轉變為用來參與位置解算的直流信號，然後選用單片機組成硬體電路，對直流信號進行採集處理並與計算機建立通信，把數據送入計算機進行位置解算，分析判別目標光源和psd器件的相對位置。
