Preliminary
303.825 MHz Hybrid Transmitter
HX3001B
Ideal for 303.825 MHz Unlicensed Transmitters in Europe
Transmission Rates of Up to 10 kbps
Compact, Surface–Mount Case with <110mm2 Footprint
The HX3001B is a miniature hybrid transmitter designed for data transmission using
on–off keyed (OOK) modulation. The transmitter is stabilized by a quartz SAW device
for long–term frequency stability. The HX3001B is recommended for data rates up to
10 kbps (100 µsec bit period). The HX3001B is designed for unlicensed
remote–control and security transmiters operating in the USA under FCC Part 15 and
in Austrailia under DTC regulations.
