Other Parts Discussed in Thread: CC1352P
Instead of using a capacitor stuffing option to switch between the internal PCB trace antenna and an external SMA antenna, I added a RF switch (Infineon BGSA12GN10) :
Here is the layout :
The problem is the output power is low by around 12dB at 915MHz :
I cut the traces going into and out of the RF switch U600 and soldered series 47pF capacitors on these cuts (this did not change the output power at all - still the same level).
Thoughts ?
