One of my customer downloaded the S parameter of HMC374, and tested it with ADS network analyzer.
BUt the result showed that the K factor is less than 1, is the S-parameter wrong or did we made something wrong with the simulation?
Thank you very much.
I reviewed the S-Parameter file posted to the web. It appears the device is conditionally stable. You can add some loss on the input or output to improve the stability. About 5 ohms in series on the input should fix the issue.
