Additional Details

The BR9371DAJ is a wideband MMIC low noise amplifier designed using GaAs process in a SOT89 general package. At 1GHz, the amplifier typically provides a gain of 22.3dB, a noise figure of 0.7dB, an output P1dB of 23.1dBm, and an output IP3 of 29.8dBm under the condition of +5V power supply. The product is compatible with low-power operation mode with the characteristics of low noise, high gain flatness, and high input P1dB, which can be applied in system with strict power consumption requirements.
