  1. In the sub block circuit design, the contents that the author had introduced include : the principle of band gap voltage reference and the design technique in low power supply ; the analysis of spike pulse noise rejection, frequency divider and dead time in oscillator and control circuit ; the selection of the width and length ratio of four switches and 2x / 1x mode change point in driver and mode selection circuits

    在子電路設計中，作者比較深入分析的內容有:基準電路的原理及低電源電壓下基準電路的設計;振蕩器和控制電路中尖峰脈沖噪聲抑制、兩分頻電路及死區時間設定;驅動及模式選擇電路中開關管的寬長比的選擇及模式轉換點的設計。
  2. For the application of direct broadcast satellite ( dbs ), a ku - band high image rejection broadband mixer is designed using ads. it appears predominant performances when compared with common single balanced mixer

    針對衛星電視直播接收系統，用ads設計了一個寬頻帶、高鏡像抑制度、低噪聲的ku波段鏡像抑制混頻器，並同普通平衡混頻器進行了對比分析，顯示了其優越的性能。
  3. This ku - band three channel receiver consists of spst modules, lna modules and image rejection mixer modules. these modules were designed and tested separately, then were assembled to the whole receiver. all the circuits were designed with small - sized devices so as to reduce the total size of the receiver. and the noise figure was considerably reduced because of the image rejection mixer

    另外，由於採用了鏡像抑制混頻器，從而使整機噪聲系數大為降低。在設計方法上，本文採用了先進的微波電路設計軟體ansoftserenade對所有的電路和系統進行設計、優化和模擬，大大的縮短設計周期，提高設計效率。
  4. Rejection band filters

    排除頻帶濾光鏡
  5. Off - band rejection

    偏帶研減
  6. Lent our - of - band interference rejection. according to the customers demands

    包括出色的帶外干擾排斥的射頻濾波。
