nRF24AP2-USB Product Specification
Table 17. Transceiver characteristics
8.1
USB interface
The USB interface electrical performance is compliant with the USB specification 2.0.
Table 18. USB interface characteristics
P_IM(4)
Input power of IM interferers at 4 and
8 MHz distance from wanted signal
g
-36

P_IM(5)
Input power of IM interferers at 5 and
10 MHz distance from wanted signal
g
-36
dBm
a. Usable band is determined by local regulations.
b. Data rate in each burst on-air.
c. The minimum channel spacing is 1 MHz.
d. Antenna load impedance = 15
Ω + j88 Ω.
e. Wanted signal level at Pin = 64 dBm. Two interferers with equal input power are used. The interferer clos-
est in frequency is unmodulated, the other interferer is modulated equal to the wanted signal. The input
power of interferers where the sensitivity equals BER=0.1% is presented.
