The XE1203F is a single-chip UHF transceiver integrated circuit intended for use as a low cost FSK transceiver to
establish a frequency-agile, half-duplex, bi-directional RF link, with NRZ (non-return to zero) data coding. Barker
encoder/decoder hardware can be activated to modulate/demodulate the transmitted signal to reduce the effects of
fixed-frequency in-band interference. The device is available in a MLPQ48 package and is designed to provide a
fully functional multi-channel FSK transceiver. It is intended for applications in the 868 MHz European band and the
North American 902-928 MHz ISM band. The single chip transceiver operates down to 2.4V and provides a low
power solution for battery-operated and power sensitive applications. The XE1203F is capable of operating data
rates up to 152.3 kbit/s, making it ideally suited for applications where high data rates are required.
