GPS/GLONASS/COMPASS LNA

Infineon's Low Noise Amplifiers for Navigation applications

GPS/GLONASS/COMPASS navigation devices, be it Smartphone, Personal Navigational Device (PND), Watch or Camera, require a Low Noise Amplifier to enhance receiver sensitivity. Most of the smartphones today feature navigation applications, which impose greater demands on linearity, size and power consumption compared to stand alone personal navigation devices (PNDs).

Product Features

  • very small footprint
  • best-in-class noise figure
  • best-in-class linearity
  • best-in-class form factor

Target Applications

  • Smartphones
  • Tablet
  • Cameras
  • Feature Phones
  • PNDs

All LNAs are developed in close association with major OEMs to satisfy all performance criteria and to enable easy and fast system design.
