Nominal Conditions
Nominal conditions are as specified below, except
otherwise specified:
+
Reference design (for measurement purposes
only) has been used. See Reference Design on
page 33.
+
Tjunct = 30° C
+
VSSA = VSSD = GND
+
VDDA = VDDD = 3.0 V
+
Transmission/reception @ 1 Mbps and up/down
chirp mode.
+
Raw data mode: no CRC, no FEC, no encryp-
tion, no bit scrambling.
+
BER = 0.001 during receive period.
+
RF output power during transmit phase = 6.3
mW (+8 dBm) EIRP measured during continu-
ous transmission.
+
All RF ports are matched according to this spec-
ification.
+
For range measurement, two identical nanoNET
systems equipped with antennae representing
1.6 dBi gain have been used. Antennae with
vertical E-polarization and omnidirectional hori-
zontal radiation pattern have been used.
+
Outdoor (open space) range measurement was
performed on flat terrain, without vegetation
higher than 0.2 m above ground, and without
visible obstacles and other objects that could
reasonably influence measurement results.
Antennae for both nanoNET systems have been
located 1.5 m above ground.
+
Indoor range measurement was performed
inside typical European office building where
both nanoNET systems were located on the
same floor.
+
All RF powers (TX output power, RX sensitivity,
etc.) are measured on the IC terminals (pins)
under impedance matched conditions.

a. It is critical that the ratings provided in Absolute Maximum Ratings be carefully observed. Stress exceeding
one or more of these limiting values may cause permanent damage to the device.
