onsemi RF and Wireless - RF Transceiver ICs AX5042-1-TW30

The AX5042-1-TW30 is a low-power CMOS RF transceiver IC designed for operation in the 400-470 MHz and 800-940 MHz ISM bands. It features a fully integrated RF front-end, modulator, and demodulator, along with a flexible communication controller that supports SPI and direct wire modes. The device supports a variety of modulation schemes including ASK, PSK, OQPSK, MSK, FSK, and GFSK, with data rates ranging from 1 to 600 kbps depending on the modulation type. The transceiver includes a programmable channel filter with a bandwidth from 4.8 kHz to 600 kHz, and it offers sensitivity levels down to -123 dBm at 1.2 kbps FSK. The transmitter can output up to +10 dBm, with a maximum of +13 dBm at 433 MHz, making it suitable for long-range applications. The AX5042-1-TW30 operates with a supply voltage range of 2.3 V to 2.8 V and consumes between 17-23 mA during receive and 13-37 mA during transmit. This product is suitable for applications such as automatic meter reading, long-range sensor readouts, and remote controls, and it is compliant with RoHS standards. The QFN28 package design minimizes the need for external components, facilitating easier integration into various systems.
