Description
These miniature RF modules provide a cost effective high performance FM Radio data link, at either 315,
433.92 or 868MHz. Manufactured using laser trimmed Thick Film ceramic Hybrid the modules exhibits
extremely stable electronic characteristics over an Industrial Temperature range. The hybrid technology uses
no adjustable components and ensures very reliable operation.
This transmitter and receiver pair enables the simple implementation of a data link at distances upto 75 metres
in-building and 250 metres open ground.
These modules will suit one-to-one and multi-node wireless links in applications including car and building
security, EPOS and inventory tracking, remote industrial process monitoring and computer networking.
Because of their small size and low power requirements, both modules are ideal for use in portable, battery-
powered applications such as hand-held terminals.

Transmitters
There are two versions of transmitter:
RTFQ1; A Dual in Line Package operating at 3.3V. This provides the most rugged mechanical fixing to
the host PCB. Power Down mode is also available.
RTFQ2; A Single in Line Package incorporating a voltage regulator for 3-12V operation. (Compatible
with many other RF transmitter modules available)
