I have followed the reference design for the CC2500 balun and pie network to match to a 50 Ohm antenna.
What are the expected losses through these external circuit components ?
After some tuning and improving I see about 11dBm loss from 0dBm output of the CC2500 to about -11dBm on a spectrum analyzer. This seems very lossy ?
I see similar losses on PCB's bought of the shelve for CC2500.
