• 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…
  • HMC920 VDrain Drops after connecting to load

    Dear Sir,

    I use HMC920 for HMC863 on my dev board, before I connect my load to HMC920, I measured the VDrain is 5,2V and VGATE is -0.9V. But after I connect to HMC863, the VDrain drops to 4.3V, Can you tell me under what conditions the VDrain will drop…

  • HMC980LP4E to bias HMC863ALC4

    Hello Community,

    as mentioned in the subject I am trying to bias the HMC863ALC4 with the HMC980LP4E. I tested the functions of the HMC980 and they seem to work as expected without any amplifier connected.
    I could measure:
    V_drain ~= 6V
    V_gate = +2.8V (if…
