High Linearity Power Amplifier

Tuning Range: 2.11 to 2.17 GHz

The GRF5521 is a high gain, two-stage InGaP HBT power amplifier designed to deliver excellent P1dB, ACLR and IM3 performance the 2110 to 2170 MHz band. Its exceptional native linearity makes it an ideal choice for transmitter applications that typically do not employ digital predistortion correction schemes.

This device is part of a complete family of externally matched linear amplifiers that cover the following frequency ranges:
GRF5506: 0.66 to 0.72 GHz
GRF5507: 0.7 to 0.8 GHz
GRF5508: 0.8 to 0.9 GHz
GRF5510: 0.88 to 0.96 GHz
GRF5517: 1.7 to 1.8 GHz
GRF5518: 1.8 to 1.91 GHz
GRF5519: 1.92 to 2.0 GHz
GRF5521: 2.11 to 2.17 GHz
GRF5526: 2.3 to 2.7 GHz
GRF5536: 3.3 to 3.8 GHz
