How to Bias HMC863 using HMC920

Hi all,

We use HMC920 to bias HMC863.

But we test the EVM and cannot tune the Vdrain=5.5V, Idrain=350mA.

But we chang R10 and Rsense as below,But Idrain is wrong.

If Rsense=340ohm, Idrain will about 485mA. But we measured 131mA.

  1. Could you advise us if there is a problem with the measurement of EVM?
  2. If we want to get Vdrain=5.5V, Idrain=350mA, could you provide a suggested circuit or R10 and Rsense value?
