The HX1005 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 HX1005 is designed specifically for
unlicensed remote-control and wireless security transmitters operating at 315.0 MHz in the USA under FCC
Part 15 regulations, in Canada under DOC RSS-210, and in Italy.
