But in millimeter-wave band, LO-RF isolation of conventional fundamental balanced mixers, which are basic building blocks of modulators, is relatively low. Larger LO leakage is one of the main factors leading to modulation precision degradation.
但是在毫米波频段,作为直接调制器基本组成单元的基波平衡混频器的LO→RF隔离度有限,所产生载波泄漏是导致调制精度恶化的主要原因之一。

实验证明,此时由于载波泄漏中噪声占主导地位,增加发射功率时接收机噪声也随之增加,对读写器距离的改善并无帮助。
