High Linearity Power Amplifier
Tuning Range: 0.777 to 0.96 GHz
The GRF5508 is a high gain, two-stage InGaP HBT power amplifier designed to deliver excellent P1dB, ACLR and IM3 performance over the 777 to 960 MHz band. Its exceptional native linearity makes it an ideal choice for transmitter applications that typically do not employ digital predistortion correction schemes.
