Semtech SX1231J
Low Power Integrated UHF Transceiver
The SX1231J is an ARIB compliant highly integrated RF transceiver which operates over all Japanese sub-GHz frequency bands. Its highly integrated digital architecture minimizes external components and provides flexibility for optimizing the system parameters and performance. The high sensitivity and exceptional blocking performance combined with optimized IIP3 maximizes the range in harshest environments.
