The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in
the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD
frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to
operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956
MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be
used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220
standard. It uses a very small number of discrete external components and integrates a
configurable baseband modem, which supports data management, modulation, and
demodulation. The data management handles the data in the proprietary fully
programmable packet format also allows the M-Bus standard compliance format (all
performance classes).资料下载
