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.
5 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.
+ T_junct = 30° C
+ V_SSA = V_SSD = GND
+ V_DDA = V_DDD = 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.
