Introduction

XL1278F is a type of low cost RF front-end transceiver module based on SX1278 from Semtech Corporation. It keeps the advantages of RFIC SX1278 but simplifies the circuit design. The high sensitivity (-136dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications. XL1278F module consists of RFIC SX1278, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don’t need to spend time in RF circuit design and choose suitable antennas for different applications. XL1278F operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up
