摘要

本文介绍了GaAs MMIC负阻芯片。这些器件用于改善平面微带谐振器结构的性能。这些负阻电路的宽带性能通过其用于补偿两个4极带通微带半波滤波器的损耗来说明，该滤波器由氧化铝衬底设计，分别以1.5 GHz和4 GHz为中心。最后，在损耗高介电常数介质衬底(/spl epsi//sub r/=36)上构建的带阻有源滤波器的实验结果也证实了他们的极大兴趣。

Broadband and tunable negative monolithic circuits for microwave active filters compensation

In this article, GaAs MMIC negative resistance chips are presented. These devices are used to improve the performances of planar microstrip resonator structures. The broadband capabilities of these negative resistance circuits are illustrated with their use to compensate for the losses of two 4-pole bandpass microstrip half wave filters designed with alumina substrate and centered respectively at 1.5 GHz and 4 GHz. Finally, experimental results of bandstop active filters built on lossy high permittivity dielectric substrate (/spl epsi//sub r/=36) and also compensated for with these monolithic circuits confirm their potential.<>
