Hello,
I have this SAW filter: **broken link removed**
It says that it has Unbalanced input (50ohm) and Balanced Output (150ohm).
In the Evaluation Circuit (page 2 in the datasheet) of this filter there is an inductor of 15nH.
Previous stage is LNA and next stage is PA.
Assuming that LNA and PA have balanced Inputs and Outputs, What do I need to do in this filter ?
and another question : Why is the input balanced to 50E and the output to 150E ?
Thanks
