SX1231J Datasheet | SEMTECH

SCRIPTION The SX1231J is an ARIB pliant highly integrated RF transceiver which operates over all Japanese sub-GHz frequency bands. Its highly integrated digital architecture minimizes external ponents and provides flexibility for optimizing the system parameters and performance. The high sensitivity and exceptional blocking performance bined with optimized IIP3 maximizes the range in harshest environments. The industries lowest sleep current, fastest wake times, and low receive current extend the battery life for any application. The transmit output power is programmable up to +17d Bm and delivers constant performance over the battery voltage lifetime. True RF™ technology enables a low-cost external ponent count (eliminating SAW filter) while still satisfying ARIB, FCC, and ETSI regulations. The device supports IEEE 15.4d/g mandatory modes.
