Introduction

SX1236 is a fully integrated ISM band transceiver capable of dual-band operation in most sub-1 GHz license-free bands with minimal external components. The device achieves a combination of high link budget and low current consumption across all operating modes. Its 143 dB link budget benefits from a low-noise CMOS receiver front-end and up to 20 dBm transmit output power. A set of internal power amplifiers is provided, allowing either fully regulated connection for constant RF performance or direct supply connection for efficiency. This makes the SX1236 ideally suited for machine-to-machine applications powered by alkaline batteries or long battery life metering applications using lithium batteries. The SX1236's low-IF architecture features fast transceiver startup time, with a demodulation design optimized for spectrally efficient modulation formats with low modulation index and Gaussian filtering. The device also supports high-performance (G)FSK modes for systems including wireless M-Bus and IEEE 802.15.4g. The SX1236 offers excellent phase noise, selectivity, receiver linearity, and third-order intermodulation intercept point, while drawing significantly lower current consumption than comparable devices.
