3.3
To allow maximum versatility, the 1320x-QE128EVB can be powered via a DC source (typically an
AC-DC converter; nominally 5 Vdc), the USB node, or an on-board battery pack with 2 AA alkaline
batteries.
3.4
The 1320x-QE128EVB provides a complete RF node which only requires a balun and antenna (external
to the MC1320x). The design uses a PCB printed metal F-antenna for an efficient, low cost solution.

The DC source or USB will automatically shutdown the battery supply
The DC source and the USB power are regulated to 3.3 V, however, the raw battery pack voltage
directly supplies the circuitry
All sources are isolated via diodes
An on/off switch and a power-on LED are provided (see
Reset)”)
Zero-ohm resistors are provided to allow isolation and measurement of various system components
(see
-1 to 0 dBm nominal output power, programmable from -27 dBm to +3 dBm typical
Receive sensitivity of <-92 dBm (typical) at 1% PER, 20-byte packet, much better than the
802.15.4 Standard of -85 dBm
Integrated transmit/receive switch
Typical range (outdoors, line of sight) of 300 meters
Optional on-board LC filter for harmonic filtering
Power Management and Measurement
Low-cost 2.4 GHz IEEE 802.15.4 ISM Band Radio
shows the RF network external to the MC1320x.
