The HX1003 is a miniature transmitter module that generates on-off keyed (OOK) modulation from an exter-
nal digital encoder (not included). The carrier frequency is quartz, surface-acoustic-wave (SAW) stabilized,
and output harmonics are suppressed by a SAW filter. The result is excellent performance in a simple-to-
use, surface-mount device with a low external component count. The HX1003 is designed specifically for
unlicensed remote-control and wireless security transmitters operating at 418.0 MHz in the United Kingdom
under DTI MPT 1340 regulations and in the USA under FCC Part 15 regulations.
