The AX5045 is a true single chip, narrow-band, ASK and FSK RF transceiver for the 60-525 MHz and 700-1050 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 maximum link budget of 158 dB at 100 bps is achieved, without the need of any additional external front end, thanks to the built-in +23 dBm integrated power amplifier. Several tens of km/miles can be achieved, even in an urban environment, using simply a single chip solution, thus reducing drastically the overall BOM.

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 3.0 - 3.6 V.

The AX5045 supports FSK, MSK, 4-FSK, GFSK, GMSK, AFSK and ASK modulations, with unrestricted and highly linear power ramp shaping. It also supports several data rates from 0.1 kbps to 200 kbps (FSK), 50 kbps (ASK), and 10 kbps (PSK).
