Additional Details

The PE91380 LNA is supplied in a surface-mount package, facilitating automated assembly and reducing overall system cost. It requires a single positive supply voltage (typically +5V) and offers excellent input and output matching to 50 Ohms. This ensures minimal signal reflection and efficient power transfer. The amplifier is designed to be unconditionally stable, meaning it will not oscillate under any load conditions, further enhancing its reliability. The device is also RoHS compliant.
