ZL70251 - Microsemi

ZL70251 Ultra-Low-Power Sub-GHz RF Transceiver

The ZL70251 ultra-low-power RF transceiver provides a wireless link in applications where power consumption is of primary importance. The transceiver’s ultralow power requirements allow the use of a coin-cell battery or energy-harvesting sources, enabling devices with extremely small form factors. The ultra-low-power device operates in unlicensed frequency .
