The AX5043 is a single-chip, narrow-bandwidth, ultra-low-power ASK and FSK RF transceiver for the 27 MHz to 1050 MHz frequency band. It offers a unique combination of ultra-low power consumption for transmit and receive operation, highest sensitivity and high selectivity. A link budget of 143 dB is achievable at 1 kbps, which can be extended to 146 dB without additional external components if built-in forward error correction (FEC) is used. The AX5043 works flawlessly down to 1 kbps in 6.25 kHz channels. An integrated voltage regulation system allows direct use of the battery with short start-up times enabling time and energy saving protocols. Transmit power and receive characteristics do not change at 1.8 - 3.6 V. AX5043 supports FSK, MSK, 4-FSK, GFSK, GMSK, AFSK and ASK modulations. In transmit mode, all modulations are shaped. For FSK, a Gaussian filter with BT=0.3 or BT=0.5 is available to meet the most stringent regulatory requirements. Power ramps can be configured without limit. The maximum output power level is 16 dBm.
