Abstract :
A near DC to 16.4 GHz wide band distributed amplifier, constructed using a 20 GHz MMIC GaAs process and optimised to operate as an optical receiver front end preamplifier, has been designed, realised and tested at 10 Gbit/s. The design uses a 75 /spl Omega/ gate line impedance to maximise the overall transimpedance gain without introducing severe bandwidth restriction.<>
