GaAs monolithic transimpedance amplifier family (TB 40) developed at R&D center of Telebras

The paper presents the development of MMIC GaAs tran-simpedance amplifiers for optical systems, carried out at R&D Center of Telebras together with University of Rome through the ITU/UNDP project. A transimpedance family was designed, in order to fulfill the needs for optical systems at different bit rates. A set of simulated characteristics of the components are presented. The results of the circuit at 2.5 GHz are showed.
