Note :
Measurement made using a POWER_TABLE entery of TX_PRE 80, INT PA63, EXT PA255. This ensures that the
Bluetooth requirements for ACP and those defined by the FCC and ETSI are satisfied over the operating
temperature rang of -5
к
to
ʳ
+45
к
. Although the design is capable of generating in excess of +18dBm, regulatory
compliance over the full temperature range of -5
к
to +45
к
will not be satisfied if the transmit power
approaches this value.
