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.
I tested two HMC920 eval boards and following settings should be ok for HMC863 in order to get Vdrain=5.5V and Idd=350mA:
Vd= 6.2V, Vldocc=5.65V, Rsense = 390 Ohm and R10 = 16.1k Ohms.
Hi Mina Wu,
We are in the process of procuring an evaluation board to provide a recommended circuit.
Let me know if you need something else.
