5 Using LoRa Technology modulation technique, RN2483 can achieve a receiver sensitivity of -146 high sensitivity combined with the integrated+14 dBm power amplifier yields industry leading linkbudget, which makes it optimal for applicationsrequiring extended range and robustness. FIGURE 1-1: RN2483 TOP VIEWLoRa Technology modulation also provides significantadvantages in both blocking and selectivity compared tothe conventional modulation techniques, solving thetraditional design compromise between extended range,interference immunity, and low-power consumption. The RN2483 Module delivers exceptional phase noise,selectivity, receiver linearity, and IIP3 for significantlylower power consumption. Figure 1-1, Figure 1-2, andFigure 1-3 show the top view, the pinout, and the blockdiagram of the Module .
