DEVICE OVERVIEW
The RN2483 transceiver module features LoRa
Technology RF modulation, which provides long range
spread spectrum communication with high interference
immunity.
Using
LoRa Technology
modulation
technique,
RN2483 can achieve a receiver sensitivity of -146 dBm.
The high sensitivity combined with the integrated
+14 dBm power amplifier yields industry leading link
budget, which makes it optimal for applications
requiring extended range and robustness.
FIGURE 1-1:
RN2483 TOP VIEW
LoRa Technology modulation also provides significant
advantages in both blocking and selectivity compared to
the conventional modulation techniques, solving the
traditional design compromise between extended range,
interference immunity, and low-power consumption.
The RN2483 module delivers exceptional phase noise,
selectivity, receiver linearity, and IIP3 for significantly
lower power consumption. Figure 1-1, Figure 1-2, and
Figure 1-3 show the top view, the pinout, and the block
diagram of the module.
