UMS enlarges its telecom power amplifier offer


UMS Power Amplifier product family now features:

  • Up to 4W capability
  • Efficient Tx power chain with a complete family of driver & PAs
  • High linearity compatible with latest DPD (Digital Pre Distorsion) techniques
  • Very good return loss            
  • Surface mount packages
  • On-chip power detector
  • ESD protection

The CHA6194-QXG, CHA6550-QXG and CHA6652-QXG are 3 new state of the art products within this family.


CHA6194-QXG  / HPA

The CHA6194-QXG is a new 37-40GHz High Power Amplifier delivering 1.2W of output power. This product features a high linearity with 38dBm OIP3 and a very low consumption of 6V@0.8A. It exhibits a very good return loss of 13dB and an excellent PAE of 18% at saturation.

As with the other telecom PAs in this extended family, the CHA6194-QXG integrates a power detector and ESD protection.

Main features:

  • Frequency range: 37-40GHz
  • Linear gain: 20dB
  • Psat: 31dBm
  • P-1dB: 30dBm
  • PAE: 18%
  • Return loss: 13dB
  • DC bias: 6V@0.8A
  • Package: 36L QFN 5x6

It is designed for Point To Point Radio or K‑Band Sat-Com applications.

The circuit is manufactured with a 0.15µm gate length GaAs pHEMT process. 


CHA6550-QXG  /  PA

The CHA6550-QXG is a new 17-23.6GHz Power Amplifier delivering 2.5W of output power. This product features a very high linearity with 41dBm OIP3, a low consumption with 6V@1.3A and a PAE of 26% (between 17-20GHz) and 20% (between 21-23.6GHz). This wideband circuit features a return losses of >20dB.

As with the other telecom PAs in this enlarged family, the CHA6550-QXG integrates a power detector and is fully ESD protected.

Main features

  • Frequency range: 17-23.6GHz
  • Linear gain: 22dB
