HMC595E

Hello,

 

I am characterizing the HMC595E  and I am having trouble meeting some of the performance specifications shown in the data sheet for this part. I am not able to get a 50 ohm match on any of my RF pins. I am only getting about -10dB to -11dB of return loss at 2.3Ghz and about -12dB to -13dB at 2Ghz and require 5-10 B lower on these measurements. Do the control pins need any kind of bypass caps or

series inductors to obtain these performance specifications? The evaluation board drawings do not show any kind of components for these pins, Any information you can provide would be greatly appreciated. Also I see that the device is on Last Time Buy, what is the recommended replacement?

 

Best Regards.
