ORDERING INFORMATION

DESCRIPTION

The HP3 RF transmitter module is the third

generation of the popular HP Series. Like its

predecessors, the HP3 is designed for the cost-

effective, high-performance wireless transfer of

analog or digital information in the popular 902-

928MHz band. HP3 Series parts feature eight

parallel selectable channels, and some versions

also add direct serial selection of 100 channels.

To ensure reliable performance, the transmitter

employs FM / FSK modulation and a micro-

processor controlled synthesized architecture.

Both SMD and pinned packages are available.

When paired with an HP3 receiver, a reliable

link is created for the transfer of analog and

digital information up to 1,000 feet. As with all Linx modules, the HP3 requires no

tuning or additional RF components (except an antenna), making integration

straightforward, even for engineers without prior RF experience.
