Ultra-LNA with Shutdown Tuning Range: 3.0 – 6.0 GHz

The GRF2083 is a broadband, linear, ultra-low noise amplifier designed for small cell, wireless infrastructure and other high performance RF applications requiring ultra-low NF, high gain and linearity.

The device features and integrated shut down function which places the device into a high-isolation shut down state.

GRF2083 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
