مضخم الترددات اللاسلكية (بالإنجليزية: RF power amplifier) هو مضخم إلكتروني يستخدم لتحويل إشارة ترددات لاسلكية منخفضة الطاقة إلى إشارة بسعة أكبر بكثير، وإعادة إرسالها إلى هوائي الإرسال. (ar) Un amplificateur de puissance radiofréquence (amplificateur de puissance RF) est un type d'amplificateur électronique qui convertit un signal radiofréquence de faible puissance en un signal de puissance plus élevée. En règle générale, les amplificateurs de puissance RF pilotent l'antenne d'un émetteur. Les objectifs de conception incluent souvent le gain, la puissance de sortie, la bande passante, l'efficacité énergétique, la linéarité (faible compression du signal à la sortie nominale), l'adaptation d'impédance d'entrée et de sortie et la dissipation thermique. (fr) A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency signal into a higher-power signal. Typically, RF power amplifiers drive the antenna of a transmitter. Design goals often include gain, power output, bandwidth, power efficiency, linearity (low signal compression at rated output), input and output impedance matching, and heat dissipation. (en) |
