Ideal for 433.92 MHz Unlicensed Transmitters in Europe
Meets the Most Stringent European Remote-Control Regulations
Compact, Surface-Mount Case with <90 mm

Footprint
The HX1000 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-to-use, sur-
face-mount device with a low external component count. The HX1000 is designed specifically for unlicensed
remote-control and wireless security transmitters operating in Europe under ETSI I-ETS 300 220 and in Ger-
many under FTZ 17 TR 2100.

NOTES:
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 manufac-
turer.
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 T
C
= +25°C ± 2°C, test load impedance = 50

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.

Notes:
1.
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 appli-
cations, a resistor can also be used.
For ESD protection.
