We have the questions about the HMC630LP3E.
1. About the application circuits in the datasheet, dc blocked capacitor on the RFOUT is C3 = 5pF.
We think the C3 = 5pF is very small value.
How to select is this value ?
2. Is there a S-parameters file for the EVB (117198-HMC630LP3) ?
- I agree on this. I would try with this and lets say 100pF and see f there is difference.
- S-parameters depends on I and Q, therefore we would need to have s2p for all IQ combinations.
