WIRELESS & SENSING SX1236 - 137 MHz to 1020 MHz Low Power Bi-Band Transceiver SX1236 DATASHEET GENERAL DESCRIPTION The SX1236 is a fully integrated ISM band transceiver capable of bi-band operation in most un-licensed bands in the sub-GHz space with a minimum of external components. It offers a combination of high link budget and low current consumption in all operating modes. The 143 dB link budget is achieved by a low noise CMOS receiver front end and up to +20 dBm of transmit output power. .

WIRELESS & SENSING SX1236 - 137 MHz to 1020 MHz Low Power Bi-Band Transceiver SX1236 DATASHEET GENERAL DESCRIPTION The SX1236 is a fully integrated ISM band transceiver capable of bi-band operation in most un-licensed bands in the sub-GHz space with a minimum of external components. It offers a combination of high link budget and low current consumption in all operating modes. The 143 dB link budget is achieved by a low noise CMOS receiver front end and up to +20 dBm of transmit output power. A set of internal power amplifiers are provided permitting either fully regulated - for constant RF performance, or direct supply connection - for optimal efficiency. This makes SX1236 ideal for either M2M applications powered by alkaline battery chemistries or long battery life metering applications using Lithium battery chemistries. The Low-IF architecture of the SX1236 sees fast transceiver start times and demodulation predicated towards low modulation index and gaussian filtered spectrally efficient modulation formats. This device also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The SX1236 delivers exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
