BR9641FDJ is a broadband high-performance MMIC gain amplifier designed using GaAs process. Covering a frequency range of 0.02GHz~8GHz, the amplifier is internally matched to 50 ohms, and only requires an external RF choke and blocking/bypass capacitors. The amplifier contains on-chip active bias network to ensure that the quiescent current is not affected by temperature. The amplifier has the characteristics of high gain flatness and high linearity when powered by a single supply operation of +5V in normal operation mode. The product is compatible with low-power operation mode to meet the requirements of applications with stringent power consumption demands.
