DESCRIPTION
The LT Series transceiver is ideal for the bi-
directional wireless transfer of serial data, control, or
command information in the favorable 260-470MHz
band. The transceiver is capable of generating
+10dBm into a 50-ohm load and achieves an
outstanding typical sensitivity of -112dBm. Its
advanced synthesized architecture delivers
outstanding stability and frequency accuracy, and
minimizes the effects of antenna pulling. When
paired, the transceivers form a reliable wireless link
that is capable of transferring data at rates of up to
10,000bps over distances of up to 3,000 feet.
Applications operating over shorter distances or at
lower data rates will also benefit from increased link reliability and superior noise
immunity. Housed in a tiny reflow-compatible SMD package, the transceiver requires
no external RF components (except an antenna), which greatly simplifies integration
and lowers assembly costs.
