ZL70250 Ultra-Low-Power Sub-GHz RF Transceiver

The ZL70250 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 methods, enabling devices with extremely small form factors. The ultra-low-power device operates in unlicensed frequency b.
