## Description

Description:The SX1278 transceivers feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.Using LoRa modulation technique SX1278 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness.Feature:1>.LoRaTM Modem 168dB maximum link budget2>.+20dBm - 100mW constant RF output vs. V supply3>.+14dBm high efficiency PA4>.Programmable bit rate up to 300kbps5>.High sensitivity: down to -148dBm6>.Bullet-proof front end: IIP3 = -11dBm7>.Excellent blocking immunity8>.Low RX current of 9.9mA, 200nA register retention9>.Fully integrated synthesizer with a resolution of 61Hz10>.FSK, GFSK, MSK, GMSK, LoRa and OOK modulation11>.Built-in bit synchronizer for clock recovery12>.Preamble detection13>.127dB Dynamic Range RSSI14>.Automatic RF Sense and CAD with ultra-fast AFC15>.Packet engine up to 256 bytes with CRC16>.Built-in temperature sensor and low battery indicatorParameter:1>.Model: RA-022>.Work Voltage:DC 1.8V-3.7V3>.Emission current:120mA(+20dBm)4>.Receiving current:10.8mA5>.Communication Protocol:SPI6>.Work frequency:420M~450MHz7>.Work Temperature:-25&#x2103;~85&#x2103;8>.Work Humidity:5%~95%RH9>.Size:23*18*13mmApplications:1>.Automated Meter Reading2>.Home and Building Automation3>.Wireless Alarm and Security Systems4>.Industrial Monitoring and Control5>.Long range Irrigation Systems
