AX5243
Advanced High Performance
ASK and FSK Narrow-band
Transceiver for
27 - 1050 MHz Range
OVERVIEW
The AX5243 is a true single chip ultra−low power narrow−band
CMOS transceiver for use in licensed and unlicensed bands from 27
and 1050 MHz. 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.
