Modified distributed amplifier to improve low frequency efficiency and noise figure

摘要

A distributed amplifier system has a predetermined output impedance and input impedance and includes an input transmission circuit; an output transmission circuit; at least two amplifiers connected between the input and output transmission circuits; an input termination on the input transmission circuit; and a feedback output termination on the output transmission circuit connected back to the input transmission circuit for reducing low frequency loss while maintaining the predetermined output impedance and input impedance.
