Ideal for 868.35 MHz Unlicensed Transmitters in Europe
Transmmission Rates of Up to 19.2 kbps
Compact, Surface-Mount Case with <110 mm2 Footprint
The HX4007B 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 HX4007B is recommended for data rates up to
19.2 kbps (52 sec bit period). The HX4007B is designed specifically for unlicensed con-
trol security and data links certified and operating under ETSI I-ETS 300 220 certifca-
tion.
