HI,

 

I was testing HMC406 amplifier.

I am facing issue of HMC406. It is drawing too much current almost 600mA. Even we tried to control the VDD current by adjusting VPD. But even then problem persists. With Vpd = 0 also current drawing 500mA. Please help to know what is the problem.

 

FYR, We used the same reference schematic.

 

Regards,

Sai
