音頻放大器
  • tone : n 托恩〈姓氏〉。n 1 調子，音調；音色;音樂。2 語調，語氣；（報刊等的）論調。3 格調，風格；風氣，氣...
  • amplifier : n. 1. 【電學】擴大器；擴音器。2. 放大鏡；放大器。
  1. Test results show that under 2 - tone test in 5mhz tone spacing, the power amplifier system achieves - 50dbc imd3 with 20w output power, improved 20db in imd3 compared with the one without linearity. estimated value of aclr comes to 53db, which satisfies the 3gpp requirement for wcdma base - station transistor. further tests with alterative input power indicate a steady suppression to the imd3 controlled by the adaptive system

    測試結果表明，自適應前饋功放系統在雙音輸出功率20w時三階交調系數小於- 50dbc ，鄰通道泄漏抑制比（ aclr ）的估算結果大於53db ，在理論上滿足3gpp對wcdma基站發射機的指標要求。
  2. Measurements of the electrical properties of transmitting tubes - measuring methods of dual tone inter - modulation distortion of linear amplifier tubes

    發射管電性能測試方法線性放大管雙音互調失真的測試方法
  3. Alarm tone amplifier

    報警聲頻放大器
  4. In order to verify memory effects of nonlinear power amplifier ( pa ) and to design and optimize pa with reducing memory effects, this paper analyzes existence of electrical and thermal memory effects with different tone spacing two - tone input signal and modulated signal source through mathematical derivation and advanced design system ( ads ) software simulation, and presents a method which can optimize pa with memory effects

    摘要為了證實非線性功放記憶效應的存在同時為了設計和優化功放以減小記憶效應，通過理論推導和ads模擬的方法分析了不同間隔的雙音輸入和調制輸入的情況下電記憶和熱記憶效應的存在，同時提出了種優化功放記憶效應性能的方法。
