AX5051 universal SRD RF transceiver |
Universal and high flexibility
AX5051 is a universal low cost single-chip RF transceiver for the
433/868/915 MHz SRD bands. It is typically used for medium distances up to 2 km. The supported data rates for this transceiver are 40 - 600 kbps.
The AX5051 transceiver consists of an integrated RF
front-end with modulator and demodulator, flexible communication
controller and integrated voltage regulator. Base band data processing
is implemented in the integrated communication controller for
user-friendly communication and configuration via SPI interface. The
integrated framing enables the use of low cost external
micro-controllers.
AX5051's flexibility, low cost and excellent RF performance make it ideal for a wide range of SRD applications.
