radio frequency amplifier 中文意思是什麼

radio frequency amplifier 解釋
射頻放大器
  • radio : n. 1. 無線電訊[電報，電話]；無線電，射電。2. 無線電廣播；無線電（廣播）臺。3. 收音機。vt. ,vi. 用無線電傳送[廣播]；（向…）作無線電廣播[傳送]；用X射線拍照；用鐳醫治。
  • frequency : n. 1. 屢次，頻仍，頻繁。2. （脈搏等的）次數，出現率；頻度；【物理學】頻率，周率。
  • amplifier : n. 1. 【電學】擴大器；擴音器。2. 放大鏡；放大器。
  1. Since the envelope of modulated signal fluctuates, these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ). so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )

    但包絡變化的調制信號經過非線性射頻功放后會產生交調分量，因此必須採用線性化技術來減少由此產生的鄰道干擾。
  2. The lower resistance should select properly, too big to make radio frequency signal drive collector current too little, too small to make amplifier instable easily

    下偏電阻要選取適中，過大會使射頻信號推動集電極電流的能力過小，過小容易使放大器不穩定。
  3. Adaptive predistortion radio frequency power amplifier linearization

    自適應預失真射頻功率放大器線性化
