Hello,
I am trying to use TCM2-33WX+ as it has a low phase and amplitude imbalance.
On TSW40RF82EVM, I have made the following mods.
1. populate L7, L8, R382 and R380.
2. remove R381 and R386.
3. Connect J40 TCM2-33WX+ secondary pin 3.
4. Connect J39 to TCM2-33WX+ secondary dot pin 4.
5. Output on primary
But my signal level is reduced by about 9 dB compared to the on the board balun.
Do I need to populate R369?
What should be the voltage at the point where R386 and L7 meet?
Please let me know.
Thank you.
