Semtech SX1236
137 MHz to 1020 MHz Low Power Bi-Band Transceiver
The SX1236 is a fully integrated ISM band transceiver capable of bi-band operation in most 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.
