a. Usable band is determined by local regulations.
b. Data rate in each burst on-air.
c. The minimum channel spacing is 1MHz.
d. Antenna load impedance = 15 Ω + j88 Ω .
e. For 250 kpbs sensitivity, frequencies which are integer multiples of 16MHz (2400, 2416 and so on) sensi-

g. Wanted signal level at Pin = -64dBm. Two interferers with equal input power are used. The interferer clos-
h. Measured with 10-bit resolution, single-ended input and VDD as reference.
i. DNL given as (abs(DNL
j. INL given as (abs(INL
k. Defined as the deviation of the first code transition (000...000) to (000...001) from the ideal.

est in frequency is unmodulated, the other interferer is modulated equal with the wanted signal. The input
power of interferers where the sensitivity equals BER = 0.1% is presented.
