Ultra-low-power 2.4 GHz transceiver for Bluetooth 5.3, 802.15.4 and IoT

Overview

icyTRX for the most demanding low-power applications

The icyTRX ultra-low-power RF transceiver is designed to meet standards such as Bluetooth Low Energy (BLE), 802.15.4 PHY Layer (e.g. ZigBee), and proprietary standards with data rates from 62.5 kBit/s up to 4 Mbit/s. icyTRX offers 5.3 mW consumption in receive mode from a 1.0 V supply. icyTRX is a complete transceiver that is designed for miniaturization, yielding an area of analog RF of less than 1 mm2 in 55 nm CMOS, requiring minimal external components thanks to high degree of integration. icyTRX is designed for easy integration into ASICs and SoCs.
