Looking to find out the difference between HMC472LP4 and HMC472ALP4. I see the spec differences, but would like to know what changed. Die revision? Process change? Complete redesign?
The HMC472ALP4 is the drop-in replacement of the HMC472LP4. It uses different process and is from a different foundry as the original HMC472LP4. The HMC472ALP4 performances supersede the HMC472LP4; with improved performances on insertion loss, return losses, switching response, Power compression, IIP3 and ESD handling. The improvement on power handling is significant on the HMC472A, approximately 10dB better on both input P0.1dB and IP3 as compared to the HMC472.
