- I needed to change the central frequency a little to 2.4 GHz, so I implemented 1.1pF in input side of the RF2126 module instead of 1pF for C1 and C2. To get 1.1pF, two 2.2pF 0805 in series were used.
- 20 dB attenuator at the output of the RF2126 module:

- no attenuator at the output of the RF2126 module:
