摘要
随着雷达、电子对抗和无线通信等技术的不断发展,宽带、超宽带通信技术的日新月异,宽带微波低噪声放大器处于宽带接收系统的前端,决定着整个通信系统的工作带宽、噪声系数和增益等技术指标,在整个通讯系统中占有重要地位。
With the rapid development of radar, ECM and wireless communication technology, and the changes and improvement of the technologies of broadband and ultra-wide band, the broad ban amplifier with low-noise amplifiers is located in the front-ends of broad band receivers. It determines the band width, noise figure and gain of the whole communication systems, and plays important role in the whole communication systems.
