A double-balanced Gilbert structure with current injection is used according to the analysis of mixer noise and gain.
通过对混频器噪声机理的分析，在原有的结构上增加了电流注入模块。

The optimal intensity noise suppression of a Fabry-Perot (FP) laser is experimentally acquired by relatively strong external optical injection locking technology.
采用较强的外注入光锁定FP激光器，获得了理想的强度噪声抑制效果。
3
The noise from injection and bubbling has the character of wide frequency band and high noise level.
