The QPB8808 draws approximately 525 mA of current from a single +12V power supply, providing about 20 dB of gain and excellent linearity. Users can adjust the bias current using an external voltage, enabling the QPB8808 to be used in applications such as frequency multipliers or in low-power system applications. 

The QPB8808 is packaged in the industry-standard 40-pin 5 x 7 mm QFN package. There are exposed tabs (EP) exposed below the device, which are used for thermal grounding and electrical grounding.
