Hi,
Thanks for everyone's response. While it is quite difficult to check the capacitive loading due the capacitance values being small (8pF), I did check the ceter frequency of the radiate spectrum and it seems to be always at 840Mz regardless of what I set the SmartRF Studio settings. Also the spectrum seems a bit spread out compared ti that of the standard EB.
The schematic is attached. I would appreciate any thoughts on why the center frequency does not vary based on the SmartRF setting.
Best,
