RF amplifier

基本解釋

The first step in the RF amplifier design is to check if the transistor is unconditionally stable.
微波放大器設計中，首要考慮的問題是管子的穩(wěn)定性。
Generally speaking, many MRI system manufacturers often purchase RF amplifier and gradient amplifier from the third party company, but they rarely buy the spectrometer.
縱觀全球，不少MRI系統(tǒng)廠家外購射頻功放和梯度放大器，但很少有外購譜儀的。
In this work, a stable SAW oscillator based on SAWR (surface acoustic wave resonator) was designed. It contains an RF amplifier and a necessary LC phase shifter network.
首先基于聲表面波諧振器（SAWR），采用射頻放大器和必要的LC移相網(wǎng)絡，設計出輸出頻率穩(wěn)定的振蕩器。
