CC-ANTENNA-DK2: Board #5 and Board #8 possible documentation error

Part Number: CC-ANTENNA-DK2

Hi,

Board #8 does not mention which switch is used (U2). I assume it is the same switch as in board # 5 (PE4259SCBECT-Z). R22 on board #5 is 8.2 kOhm. The equivalent resistor R20 on board #8 is 8.2 Ohm. I assume this is an error, and should also be 8.2 kOhm.

Regarding this shunt resistor: Why is it there? The RFC pin in the switch datasheet does not mention any pull-down resistor here (or filter). I understand that the series caps are for DC blocking.

Where can I find exact dimensions for the antennas in order to implement them in my design?

Are there gerber files and schematics available?
