Preliminary
869.475 MHz Hybrid Transmitter
HX3005B
Ideal for 869.475 MHz Unlicensed Transmitters in Europe
Transmission Rates of Up to 19.2 kbps
Compact, Surface–Mount Case with <110mm2 Footprint
The HX3005B 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 HX3005B is recommended for data rates up to
19.2 kbps (52 sec bit period). The HX3005B is designed specifically for unlicensed
control security and data links certified and operating in the USA under FCC Part
15.249 and in Canada under TRS RSS–210.
