This product is pin to pin compatible with our CHA4253aQQG.

Main features:

  • Frequency range: 21-27.5GHz
  • Linear gain: 25dB
  • Gain control: 15dB
  • OIP3: 32dBm
  • P-1dB: 19dBm
  • DC bias: 4V@180mA
  • Package: 16L QFN 4x4


The CHA3660-QQG is designed for a wide range of applications including professional and commercial communication systems.

This product is manufactured using a robust 0.25µm gate length GaAs pHEMT process.
