The BR9388DAJ is an integrated Bypass low noise amplifier covering a frequency range of 500 MHz to 4 GHz. It is internally matched to 50 ohms, requiring only external DC‑blocking capacitors at the RF input and output ports. The on‑chip active bias network ensures that the quiescent current remains stable against threshold voltage and temperature variations. At 2 GHz, the device typically provides a small‑signal gain of 22.1 dB, an insertion loss of 0.8 dB, an output P1dB of 18.6 dBm, and a noise figure of 0.7 dB. This product features low power consumption and high gain flatness across a wide bandwidth, making it suitable for high‑performance transceiver systems.
