  1. Secondly, the mmic 20 - 40ghz hmmc - 5040 amplifier is used to realize the phemt frequency converter. the feasibility of up / down converter using phemt sub - harmonic mixing is validated by the experimental results. at last, on the base of phemt multiplying, amplifying and gate mixing, the

    之後研究了採用hp公司的20 - 40ghz放大器晶元( hmmc - 5040 )設計製作phemt ( pseudomorphichighmobiletransistor )變頻器,通過測試,給出了實驗結果,並通過實驗驗證了採用phemt二次諧波混頻模式,實現上下混頻的可行性。
  2. This paper include the following parts. firstly the sine exciting - voltage is guaranteed by direct digital synthesize technology ; secondly the digital output of cos ( 9 ) and sin ( 9 ) are generated by microcontroller ; thirdly the two voltage signals which are the product of the two former signals gained by the multiplying d / a converter, being filtered and amplified, have constant frequency, and one amplitude has sine function relationship of with the input angle, and the other amplitude has cosine function relationship of with the input angle ; finally the two signals are acquired and analyzed by relative instrument and software

    主要由以下幾部分組成:用數字頻率合成技術( dds )產生正弦激勵電壓信號u _ msin ( t ) ;用單片機產生幅度的數字量輸出sin ( )和cos ( ) ;用乘法型d a轉換器實現激勵電壓和幅度的乘積,並通過濾波器和功放后即得到頻率固定,幅值隨輸入角成正餘弦變化的電壓信號;最後用數據採集卡採集輸出信號,顯示波形並進行頻譜分析。
