Ultra-LNA with Shutdown
Tuning Range: 1.4 to 2.7 GHz

The GRF2081 is a broadband, linear, ultra-low noise amplifier designed for small cell, wireless infrastructure and other high performance RF applications requiring the absolute lowest possible NF, high gain and outstanding linearity.

The device delivers industry leading NF and IP3 over 1.7 to 2.7 GHz using a single tune. VDD can be varied from 2.7 to 5.0 volts depending on application requirements.

GRF2081 is a member of a family of pin compatible, ultra-low noise devices which cover a wide range of frequency bands with industry leading NF and gain:

  • GRF2080: 0.4 to 1.5 GHz
  • GRF2081: 1.4 to 2.7 GHz
  • GRF2082: 2.3 to 3.8 GHz
  • GRF2083: 3.0 to 6.0 GHz
