  5. This subject aim at designing a linear power amplifer whose output power is 40w for 225 - 450mhz band. but it seems not easy to finish the task because of this power amplifier own unique requirements including high output power, broad working frequency band, high linearity, and flat gain. due to the complexity involved, theoretically several soltuions are derived in the final scheme such as broadband matching technology, power - retreat, power synthesize, automatic power control and negative feedback. in addition, the design will be optimized by eda software and the final test result indicates that our design is successful

    本課題的目標是研製一個輸出功率為40w的225 450mhz的線性功率放大器。由於該功放要求輸出功率大，工作頻帶寬，帶內增益波動小，線性度高，所以其終合設計難度大。鑒于這個原因，在理論設計上筆者採用了寬帶匹配、功率合成、功率回退、負反饋、自動功率控制等技術；在實踐中精心設計電路，並且配合eda軟體模擬，最終達到所要求的指標。
