1. Lower transmit power (i.e. Class 2) can be obtained by programming the radio init power table via software parameter
2. Power of GFSK part.
3. Relative power of EDR part compared to the GFSK part.
4. At antenna with maximum output power, filter attenuation of 2.3 dB.
5. Phase noise will add maximum [-10 kHz;10 kHz] for worst case clock 270 mVpp at 13 MHz.
6. Worst case clock 270 mVpp at 13 MHz. Measurement according to EDR RF test spec V2.0.E.3 [].
7. With maximum output power (BR or EDR).
8. Measured on reference design STLC2555_rev1.1 following eBOM and layout recommendations.
9. Measurement bandwidth.
10. Transmitting DH5 packets.
