High Linearity Power Amplifier
The GRF5112 is a GaAs pHEMT Power Amplifier that can be tuned to deliver excellent ACLR and OIP3 performance over the 100 to 2700 MHz band. Its exceptional native linearity makes it an ideal choice for transmitter applications that typically do not employ digital predistortion correction schemes.
Please consult with the GRF applications engineering team for custom tuning/evaluation board data.
