The BR9395DAJ is a low noise amplifier with an integrated shutdown function, covering a frequency range from 30 MHz to 4.5 GHz. It is internally matched to 50 ohms, requiring only external DC-blocking capacitors at the RF input and output ports. An on-chip active bias network ensures stable quiescent current by compensating for threshold voltage and temperature variations. Operating from a single power supply of +3.3V to +5V, the device incorporates an integrated shutdown bias function, enabling operation in TDD systems. The amplifier offers low noise, high gain flatness, and high linearity across a wide bandwidth, making it suitable for applications demanding high linearity and low noise performance.
