I have a VCO whose output is 100 Ohm differential coupled microstrip. Can I connect those two traces to ADF4158's RFinA and RFinB? And is those two pins high impedance? Should I add some impedance matching resistors?
The RF input pins are ~50 Ω ideally so 100 Ω differential is fine.
You still need to AC couple the RF signals - we typically recommend 100 pF.
Hi, do you mean 50ohm differential input impedance, or 50ohm input impedance for each RFINA/RFINB? Thanks.
50 Ω input impedance for each RFINA/RFINB.
