AX5043 - Narrow-band Ultra Low Power RF Transceiver IC

The AX5043 is a single chip narrow-band RF transceiver for the 70MHz to 1050MHz frequency bands.

The AX5043 is a single chip narrow-band ultra-low-power ASK and FSK RF transceiver for the 27 MHz to 1050 MHz frequency bands. It offers the unique combination of ultra-low power consumption for transmit and receive operation combined with highest sensitivity and high selectivity. A link budget of 143 dB at 1 kbps is achieved, if the built-in forward error correction (FEC) is used this can be extended to 146 dB without extra external components. The AX5043 works perfectly down to 1 kbps in a 6.25 kHz channel.

An integrated voltage regulation system allows the direct use of batteries and short start-up times enable time- and energy-efficient protocols. Transmit power and receive characteristics do not change over the supply voltage range of 1.8 - 3.6 V.

The AX5043 supports FSK, MSK, 4-FSK, GFSK, GMSK, AFSK and ASK modulations. In transmit mode, all modulations are shaped. For FSK gaussian filters with BT=0.3 or BT=0.5 are available to meet the most stringent regulatory requirements. Power ramping can be configured without restrictions. Maximum output power level is 16 dBm.

Key Features:

  • Carrier frequency range 27 - 1050 MHz
  • Ultra-low power
  • Constant TX output power over the full VDD range of 1.8 - 3.6 V
  • Fully autonomous lowest power wake-on-radio mode (500 nA)
  • Packet RX/TX without microcontroller intervention
