Low Cost Miniature UHF Single
Channel Transceiver for High
Bitrate Digital Transmissions
The ARF2104 module is a low cost solution for two-way RF links
over several hundred meters. It provides a serial communication
channel with selectable bitrate between 4k, 16k, 32k and 64
kbits/s.
ARF2104 is based on the XEMICS XE1201 single chip device,
working at 433.9 MHz according to the European standard ETS
300-220 / ETS 300-683. It is available as a ready-for-use
daughter board. No trimm ing needed !
