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.
Accurate digital received signal strength indication (RSSI)
Fast settling automatic frequency control (AFC) algorithm for
very short preambles
Autonomous automatic gain control (AGC) algorithm
On-chip ARM Cortex-M0 processor performs the following
functions:
The ADF7030 features an on-chip ARM® Cortex®-M0 processor
that performs radio control and calibration, as well as packet
management.
