Abstract
A quasi-lumped element impedance matching technique was developed for a multi-octave bandwidth FET amplifier. The lumped elements were realized by parallel capacitors, high impedance band wires and etched lines on a 0.170 x 0.085 x 0.010 inch alumina substrate. A two-stage amplifier has been constructed using this method and yields 17/spl plusmn/ dB gain and 3.5 dB maximum noise figure over 1.75 to 6.0 GHz band.
提出了一种适用于多倍频宽场效应管放大器的准集总元阻抗匹配技术。集总元件由并联电容器、高阻抗带线和蚀刻线在0.170 x 0.085 x 0.010英寸的氧化铝基板上实现。用这种方法构造了一个两级放大器，在1.75至6.0 GHz频段产生17/spl plusmn/ dB增益和3.5 dB最大噪声系数。
