Abstract
Designing a DC coupled wide bandwidth amplifier with a low noise figure for a known source impedance creates problems when using op-amps or discrete transistor designs. This paper explores using today's wide bandwidth op-amps in a composite design to provide the best performance characteristics with the lowest noise figure for a 50 ohm source impedance.
