High Linearity Power Amplifier
Tuning Range: 1.8 to 2 GHz

The GRF5518 is a high gain, two-stage InGaP HBT power amplifier designed to deliver excellent P1dB, ACLR and IM3 performance over the 1800 to 2000 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 Guerrilla RF applications engineering team for custom evaluation board data.
