采用SiGe-HBT工艺实现了两种43Gbit/S数据传输宽带放大器：一种是具有36dB差分增益、26 GHz带宽的差分集总限幅放大器；另一种是具有820 GHz增益带宽积的两级分布式放大器。此外，对于超过43Gbit/S的应用，采用更先进的SiGe工艺(ft，Fmax>；200 GHz)实现了分布式放大器。该放大器获得了13分贝的增益和超过80 GHz的带宽，这是迄今为止报道的硅基放大器的最高带宽。
Two broadband amplifiers for 43 Gbit/s data transmission were realized in a SiGe-HBT technology with ft = 120 GHz and fmax = 100 GHz: a differential lumped limiting amplifier with 36 dB differential gain and 26 GHz bandwidth and a two stage distributed amplifier with a gain-bandwidth product of 820 GHz. Additionally, for applications beyond 43 Gbit/s, a distributed amplifier was realized in a more advanced SiGe process (ft, fmax > 200 GHz). This amplifier achieves 13 dB gain and more than 80 GHz bandwidth, which is the highest bandwidth reported so far for Si-based amplifiers.
