Cbypass: This capacitor is used for DC line bypass (100pF is recommended.)
DD
When the DC level of the connected device is GND or open, no DC blocking capacitors are required.
The DC level of each RF pin is GND.
LC circuit is recommended for IMD2 (Rx-Tx) improvement and ESD protection to Antenna pins. (For constants, see above.)
