摘要
本文介绍了一种采用MMIC元器件设计宽带增益线性渐变放大器的方法.按这种方法设计的放大器可实现增益线性渐变,输入输出匹配良好.此方法在同类放大器设计中有一定的参考价值.
This paper presents a method designing linearly variable-gain amplifier using the MMIC devices.The amplifier with 30-40 dB gain,noise figure <2. 2 and VSWR<1.5:1 is based on the two MMIC devices and attenuation network in the 50-650 MHz range.It is helpful for people to design the same type of amplifier.
