Overview: SX1231J WIRELESS & SENSING SX1231J Transceiver Low Power Integrated UHF Transceiver DATASHEET RFIO VBAT1&2 VR_ANA VR_DIG Power Distribution System LNA Σ/Δ Single to Mixers Modulators Differential RC Oscillator GND VR_PA.

General Description

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.

Key Features

  • High Sensitivity: down to -120 dBm at 1.2 kbps.
  • Robust Selectivity: 42dB at 25kHz offset.
  • Bullet-proof front end: IIP3 = -18 dBm, IIP2 = +35 dBm, 80 dB Blocking Immunity, no Image Frequency response.
  • Low current receive mode = 16 mA.
  • Low current sleep mode with register retention =100nA.
  • Programmable TX Power: -18 to +17 dBm in 1dB steps.
  • Constant RF performance over VDD voltage range.
  • FSK bit rates up to 300 kb/s.
  • Fully integrated synthesizer with a.
