CHK9013-99F and CHK9014-99F transistors

UMS has introduced 2 new GaN power bars, the CHK9013-99F and the CHK9014-99F.

 

They exhibit:

  • High power
  • High efficiency
  • Wide band capability
  • Compatibility with pulsed and CW operating modes

 

 

  CHK9013-99F CHK9014-99F
Nb of cells 8 8
Max freq (GHz) 8 13
Pout Max (W) 85 55
PAE* 65%@5GHz 50%@12GHz
Wide band capability Up to 8GHz Up to 13GHz
DC Bias VD up to 30V VD up to 30V
Technology GH25 GH25
Dimensions 0.9×4.27×0.1mm 0.88×4.27×0.1mm

 

 

These devices can be optimised in systems according to specific requirements: PAE, power, robustness…

To fine tune the overall performance, our ULRC technology, is open in foundry mode to design the needed matching elements.

UMS power bars are also available assembled in hermetic, plastic or flange packages.
