Hi. The supplied S-parameter file for the HMC634LC4 amp does not match well with what is shown for gain in its data sheet. At the two freq points that I checked, it was lower by 2 to 2.5 dB. I would have thought that the supplied file would better represent the typical results of the amp. I assume the data sheet shows typical results. Can you explain? Can you update the S-par file on the HMC634LC4 page? Thank you.
The s2p file given on the product page is still wtihin the specs, but as you said it is showing the response of a below average device.
Attached spreadsheet contains s2p data which is closer gathered from a part closer to the DS.
