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.

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.
