CMD219C4 Low noise amplfier

4-8 GHz (C Band) GaN Low Noise Amplifier MMIC

The CMD219C4 is a broadband GaN low noise amplifier MMIC housed in a leadless 4x4 mm QFN package. The CMD219C4 is ideally suited for microwave radios and C band applications where small size and high input power survivability are critical design requirements. The broadband device delivers greater than 22.5 dB of gain with a corresponding output 1 dB compression point of +17 dBm and a noise figure of 1 dB. The CMD219C4 low noise amplifier MMIC features an RF input power survivability of greater than 5 Watts.


  • High gain
  • High linearity
  • High RF power survivability
  • Low noise figure
  • Pb-free RoHS compliant 4x4 QFN package
