SX1232 系列 915MHz 超低功耗 高链路预算 集成 超高频 收发器
GENERAL DESCRIPTION
The SX1232 is a fully integrated ISM band transceiver optimized for use in the EN 300 220-1 868 MHz band in Europe and the FCC Part 15 915 MHz band in the US 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 pair of internal power amplifiers are provided permitting either fully regulated - for constant RF performance, or direct supply connection - for optimal efficiency. This makes SX1232 ideal for either M2M applications powered by alkaline battery chemistries or long battery life metering applications using Lithium battery chemistries.
