The onsemi AX5243-1-TA05 is a highly integrated RF transceiver IC designed for general ISM band applications below 1GHz. This component operates across a wide frequency range from 27MHz to 1.05GHz, supporting multiple modulation schemes including 4FSK, ASK, FSK, GFSK, GMSK, MSK, and PSK. It features a robust transmit output power of up to 16dBm and a sensitivity of -137dBm, enabling reliable communication links. Power consumption is efficient, with a receiving current draw of 6.5mA to 11mA and a transmitting current of 48mA. Data rates up to 125kbps are supported. Communication with the host processor is facilitated via an SPI serial interface. The device is housed in a compact 20-VFQFN exposed pad package, suitable for surface mounting. Operating temperature range is -40°C to 85°C, with a supply voltage between 1.8V and 3.6V. This transceiver is commonly utilized in industrial, medical, and consumer electronics sectors requiring robust wireless connectivity.
