The HX1002 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 HX1002 is designed specifically for
unlicensed remote-control and wireless security transmitters operating in the USA under FCC Part 15 and in
Australia under DTC regulations.

One or more of the following United States patents apply: 4,454,488; 4,616,197; 4,670,681; and 4,760,352.
Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer.
Applies over the specified range of operating temperature.
Applies over the specified range of operating power supply voltage.
The design, manufacturing process, and specifications of this device are subject to change without notice.
The maximum modulation bandwidth (and data rate) is dependent on the characteristics of the external encoding circuitry (not included).
Unless noted otherwise, case temperature TC = +25°C ± 2°C, test load impedance = 50 W, and modulation input is at logic HIGH.
