amplifier chain meaning in English

放大器链, 放大器通路

A novel amplifier chain which is composed of the forward wave crossed - field amplifier ( cfa ) driven directly by solid state amplifier ( ssa ) is better in performances and reliability compared with traditional three stage chain which is composed of " ssa + twta + cfa "
摘要采用固态放大器直接驱动前向波管的新型放大链与“固态-中功率行波管-前向波管”三级放大链相比较，具有更好的性能指标。
First please make sure the useful signal has very good snr before you input it to amplifiers chain , then you can calculate how much gain and nf you need to get the targeted signal amplitude and noise level , based on this you can choose the right components to design amplifiers chain
后才将其输入放大器链，接着计算获得目标信号振幅和噪声水平所需的增益与nf的大小，最后根据这些数据选择合适的器件设计放大器链路。
