SX1278規(guī)格書詳情
SX1278屬于RF/IF射頻/中頻RFID的射頻收發(fā)器IC。由Semtech Corporation制造生產(chǎn)的SX1278射頻收發(fā)器 IC射頻收發(fā)器 IC 是將發(fā)射器和接收器集成于單個封裝的半導(dǎo)體器件。收發(fā)器適用于各種射頻系列產(chǎn)品或標(biāo)準(zhǔn),例如 AISG、藍(lán)牙、ISM、VHF、Wi-Fi、蜂窩、雷達(dá)、802.15.4 和 Z-Wave。此產(chǎn)品可根據(jù)調(diào)制類型和特定協(xié)議版本進(jìn)一步分類。部分 IC 包含內(nèi)置微控制器。
GENERAL DESCRIPTION
The SX1276/77/78/79 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
Using Semtech’s patented LoRa? modulation technique SX1276/77/78/79 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.
These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The SX1276/77/78/79 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
