GENERAL DESCRIPTION

The ADF7030 is a low power, high performance, integrated

radio transceiver supporting narrow-band operation in the

169.4 MHz to 169.6 MHz ISM band. The ADF7030 supports

transmit and receive operation at 2.4 kbps and 4.8 kbps using

2GFSK modulation and transmit operation at 6.4 kbps using

4GFSK modulation.

The ADF7030 features an on-chip ARM® Cortex®-M0 processor

that performs radio control and calibration, as well as packet

management.
