High Performance, Low Power Sub-GHz RF Transceiver
ER4111 Technical Highlights
ER41XX is a family of high performance, high flexibility, low power RF transceiver IC for IOT applications. ER41XX covers 127/433/470/510/868/915MHz ISM bands in sub-GHz frequency spectrum. In addition to supporting Sub-GHz band for long range connectivity, the product also comes with NFC, which is compliant with ISO/IEC 14443-3 standard (Type A), to provide contactless short range connectivity to mobile device. The EliteRadio‐ER41XX transceiver realizes long range wireless data communication with high data rate up to 2Mbps. Its proprietary on‐chip power amplifier optimizes power consumption for applications that require either high output power up to +23dBm or low output power at 10dBm without external PA. ER41XX has excellent Rx performance in sensitivity (-102dbm sensitivity @ 100Kbps/ 915Mhz/ FSK) and is designed to provide multiple working power management modes with low RF receive current (Rx: 16mA@915MHz) as well as wake on RX (WOR) without MCU involvement to extend lifespan of battery operated devices such as electronic shelf labels, smart meters and disposable wireless sensors.
