Hi Tech support,

 

Question on HMC980LP4 and refer to 16 Jun 2015 discussion.

HMC980 problem is not yet resolved.

What is the purpose of R5 and R7 ?

Does it help the DUT to obtain igate and the VNEGFB?

How the circuitry for the CPout work with the diode?

 

Have tried your recommendation but it still does not work.

HMC980 does not provide the VDrain for the DUT.

 

Please advise.....

 

 

 

Thank you.
