Recommended Active Bias Controller for HMC1121

Is there a recommended active bias controller similar to the HMC980 available for the HMC1121 that can handle the 2200mA drain current?

    Hi,

    We do not have bias controller that go above 1.6A. However you can use 2x HMC980 to increase the supply current. Below is an example using 2xHMC980 to generate 2.4A.

     

    • Connections between the 2x HMC980:

      • Connect 2x Isense together
      • Connect 2x VDrain together
      • Connect 1x CPout to 2x Vneg
      • Use 1x resistor for Isense, and calculate resistor value for DUT Idd/

    Thanks,

    David
