Additional Details

The BR9555TA is a MMIC low noise

amplifier using GaAs process. The amplifier is

internally matched to 50 ohms with frequency

range of 30MHz ~ 1GHz, and only require an

external RF choke and blocking/bypass

capacitors. The amplifier contains on-chip

active bias network to ensures that the

quiescent current is not affected by the process

and temperature. The product, with +5V single

power supply, provides high reliability, high

linearity, low noise, general package, etc.,

which makes the product can be applied in

system with high dynamic range.
