Draft 29 April 11:11 4
The RFIC utilized in the RFM307 is AT86RF230, manufactured by Atmel. The RFIC is a
“low-power 2.4 GHz radio transceiver especially designed for ZigBee/IEEE 802.15.4
applications” according to the AT86RF230 Data Sheet. Most, if not all, subsequent
information is derived from the AT86RF230 Data Sheet. The transceiver IC is capable
of operating in the frequency range of 2405MHz to 2480MHz, divided into 16 pre-
defined channels. The adjustable transmission power is stated to be -17dBm to +3dBm,
+/-3dBm. All RF functions are controlled by an external programmed controller that can
read and write the RFIC’s internal control registers, accessed via the SPI serial digital
control interface and digital I/O control signals. See the manufacturer’s data for
additional details.
