GRF5507

High Linearity Power Amplifier

Tuning Range: 0.7 to 0.8 GHz

The GRF550is a high gain, two-stage InGaP HBTpower amplifier designed to deliver excellent P1dB, ACLR and IM3 performance over the 700 to 800 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 - 0.72 GHz
  • GRF55070.7 0.8 GHz
  • GRF55080.8 0.9 GHz
  • GRF5510: 0.88 0.96 GHz
  • GRF55171.7 1.8 GHz
  • GRF5518: 1.8 1.91 GHz
  • GRF55191.92 2.0 GHz
  • GRF5521: 2.11 2.17 GHz
  • GRF55262.5 - 2.7 GHz
  • GRF55363.4 - 3.8 GHz
