摘要

提出了一种紧凑的1.3mm × 0.83mm SiGe分布式宽带放大器。该设计利用高损耗的薄膜微带传输线元件。讨论了扩展放大器带宽的衰减补偿方法。放大器小信号增益为10.5 dB，上限3db截止频率为41 GHz。在带宽范围内21 ps的低组延迟变化使该放大器能够在40 Gbit/s光纤通信系统中运行。

Attenuation compensation techniques in distributed SiGe HBT amplifiers using highly lossy thin film microstrip lines

A compact 1.3mm x 0.83mm SiGe distributed wideband amplifier is presented. The design utilises highly lossy thin film microstrip transmission line elements. Attenuation compensation methods for extending the amplifier’s bandwidth are discussed. Amplifier small-signal gain is 10.5 dB, upper 3 dB cut-off frequency is 41 GHz. Low group delay variations of 21 ps within the bandwidth qualify this amplifier for operation in a 40 Gbit/s fibre-optic communication system.
