臺灣博碩士論文加值系統

本論文以台積電所提供SiGe 0.35um 製程實現適用於WiMAX 802.16e 之功率放大器設計與實現，運用於3.5GHz 頻帶平均輸出功率20dBm、增益將近16dBm 其中加入線性器架構提高整體功率放大器
效率，最後加入功率檢測器將功率訊號轉換成直流電壓訊號，此訊號回授給直流轉直流電源供應器IC 控制出電壓大小，改善功率放大器效率。本文將其設計方式與量測結果探討其特性與未來改善方向。

This paper used TSMC SiGe 0.35um technologies to RF power
amplifier design for WiMAX 802.16e system application. In the 3.5GHz frequency band average output power 20dBm, gain near 16dBm and joins the linearity construction to raise the overall power amplifier efficiency. Finally design the power detector to transform the power signal, this signal returns gives controls the output voltage for DC-DC IC. This design can improve the power amplifier efficiency. This paper will discuss its design way and the gauging result its characteristic and the future improves the direction.
