There's a shut down pin on the ic shown on the datasheet. Is it connected correctly? I can't see reference to it on your circuit diagram

Yes NSD is shut down pin but I normally don't connect shut down pin with others. I am not sure it's correct.

 

S

So you suggest I should use dummy RF loads instead of the electronic load.

Yes

 

I used Mbr1645 schottky diodes for boot strap.

It's not connected correctly in your schematic. Check the IC datasheet.

I think I connected correctly.

 

The problem is that even though I increase the dc supply voltage to MOSFETs, the current is not increased at all (0.0mA)

Where are you measuring the current?

 

I think I connected correctly.

No. D5 cathode should connect to VB, not to VS as you show in your schematic.

The current from dc power supply.

Thank you so much. I didn't know that. I will correct and test again.
