本文报道了一种用于100 Gbit/s光通信系统(以太网)的最先进的分布式放大器。该放大器采用InP DHBT技术,fr和fmax的截止频率值均超过275 GHz,实现了21 dB的增益和90 GHz的3 dB带宽,从而获得1太赫兹的增益带宽积(GBW)。据我们所知,这代表了迄今为止报道的任何技术中单级放大器实现的最高增益带宽产品。
This paper reports a state-of-the-art distributed amplifier intended for use in 100 Gbit/s optical communication systems (Ethernet). Using an InP DHBT technology, exhibiting cut-off frequency values of more than 275 GHz for both fr and fmax, the amplifier achieved a gain of 21 dB and a 90 GHz 3-dB bandwidth, resulting in a gain-bandwidth product (GBW) of 1 THz. To our best knowledge, this represents the highest gain bandwidth product achieved for single-stage amplifiers in any technology reported to date.
