1.

These parameters are characterized, but not tested on production device.

2.

The RF transmit power is the average power measured for the mid-channel (Channel 39).

3.

The RF transmit power is calibrated during production using the MP tool and MT8852 Bluetooth test

equipment.

4.

Test condition: VCC_RF = 1.28V, temperature +25ºC.
