HMC465LP5 not working

Question asked by Peter_Feng on Jun 7, 2018

I have bought an HMC465LP5 on an EV board. It worked before and showed a very beautiful frequency response (S21). However, it is not working now. When -2V Vgg, 1 V Vctrl and 5V Vdd was supplied according to the datasheet, there was no Idd(current). I varied the Vgg between 0 and -2 V, there was no Idd current at all?

 

I just wonder whether the amplifier has been broken or not. Is there a way that I can check whether the amplifier has been broken or some open or short circuits on the EV boards?

 

Many thanks for any help provided!

 

Best wishes,

Peter.
