Transmitter
The HX1005 is a miniature transmitter module that generates on-off keyed (OOK) modulation from an external 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-touse, 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.

2.
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.
3. Applies over the specified range of operating temperature.
4. Applies over the specified range of operating power supply voltage.
5. The design, manufacturing process, and specifications of this device are subject to change without notice.
6. The maximum modulation bandwidth (and data rate) is dependent on the characteristics of the external encoding circuitry (not included).
7. Unless noted otherwise, case temperature TC = +25°C ± 2°C, test load impedance = 50 Ω, and modulation input is at logic HIGH.
8. The maximum operating current occurs at the maximum specified power supply voltage and maximum specified operating temperature.
9. Standby current is defined as the supply current consumed with the modulation input at logic LOW.
10. Improper antenna loading affects performance of HX device.

This matching component is required only for antennas that are not
50 ohms. It is typically a chip inductor to match to stub antennas
shorter than ¼ wavelength. For very low radiated field-strength applications, a resistor can also be used.
For ESD protection.
