Hi, all,
The TX is designed to be with 5dB gain from analog baseband to RF sections, but it turns out to be -5dB, while the trace loss and cable loss have been considered. that's to say, there are 10dB difference between simulation and measurement. I could not figure out that how could this happen, anybody can give some hints, thanks a lot.
