AX50424: 400 - 470 MHz and 800 - 940 MHz narrow-band low-power paging RF receiver IC

Your paging receiver solution.

The AX50424 is a single-chip ultra narrowband RF receiver for the 400-470 MHz and 800-940 MHz bands. The AX50424 offers very long range with a small number of components.

The AX50424 transceiver consists of an integrated RF front-end with demodulator and flexible communication controller. Base band data processing is implemented in the integrated communication controller for user-friendly communication and configuration via SPI interface. The integrated matching logic guarantees exceptionally compact code for paging protocols and small CPU overhead.

The AX50424's flexibility make it ideal for paging applications such as sensor networks, access control systems or home automation applications.
