A new MPA the CHA4253-QQG
The CHA4253-QQG a new packaged 4 stage Medium Power Amplifier

The CHA4253-QQG is a packaged 4 stage MMIC Medium Power Amplifier which delivers 24dBm output power with a gain at 23dB. It delivers an optimized linearity performance in the 18GHz frequency range and a low power consumption.

It is designed for military and commercial communication systems and is particularly suited to point to point applications.

The circuit is manufactured with a 0.15µm gate length pHEMT process. It is supplied in RoHS compliant SMD package 4x4.

For those who are interested in the die form of this circuit, the CHA5350-99F MPA presents the same characteristics.


  • Frequency range: 17-24GHz
  • Linear Gain:    23dB
  • Pout@1dB comp:    24dBm
  • Output IP3:    33dBm
  • DC bias:    5V@270mA
