    摘 要:根據(jù)正弦波振蕩電路的起振原理,設(shè)計了西勒振蕩器,作為高頻功率放大電路的輸入端。利用射極跟隨器可連接于兩電路中間起緩沖作用的特性,設(shè)計了緩沖電路。整個設(shè)計末端,用一個丙類諧振功放來進一步增強輸出電壓和輸出功率。采用LTspice 軟件對設(shè)計的高頻功率放大電路特性進行模擬仿真與分析,驗證了理論分析的正確性與可行性。

    Abstract: According to the vibration principle of sine wave oscillation circuits, the Seiler oscillator circuit was designed to act as the input terminal of high frequency power amplifier. The Emitter follower could be connected to the middle of the two circuits to become the buffer circuit. At the end of the whole design, the output voltage and output power could be further enhanced by a class C resonant power amplifier. The software, LTspice was adopted to carry out simulation and analysis for the designed circuit characteristics of the high frequency power amplifier, which verifies the validity and feasibility of the theoretical analysis.
    Key words: Seiler oscillator circuit; emitter follower; class C resonant power amplifier; LTspice simulation
