I'm planning to use the ADF4150HV in my application - I have the evaluation board and it's all looking good so far.
However, I'll need to filter the device output and to design the filter properly I need to know the output impedance of the RFOUT+ / RFOUT- pins. S-parameter data would be ideal, but there's nothing much in the datasheet, only some hints that it's relatively high impedance and a little bit capacitive.
Is there anyone on here who has this data and could send it to me?
I’m afraid we do not have the S-parameters measurement results for ADF4150HV available at the moment. The only help I can offer now is the S-parameters results for ADF4150 (attached files for measurements with output power -1 dBm, -4 dBm and +2 dBm). ADF4150 and ADF4150HV have the same output stage, however, there is a difference in bonding of both parts as they have different package.
Thanks very much - those will get me started at least (and I might have a guess at the packaging differences).
