AX5051
Advanced Multi-channel
Single Chip UHF Transceiver
OVERVIEW
The AX5051 is a true single chip low−power CMOS transceiver
primarily for use in SRD bands. The on−chip transceiver consists of a
fully integrated RF front−end with modulator, and demodulator. Base
band data processing is implemented in an advanced and flexible
communication controller that enables user−friendly communication
via the SPI interface.
