FM-RRFQ1-433 is an 433.92MHz FM receiver hybrid module, These miniature RF modules provide a cost effective high performance FM radio data link at 433.92MHz. Manufactured using laser trimmed thick film ceramic hybrid, the modules exhibit extremely stable electronic characteristics over an industrial temperature range. Manufacture on a ceramic substrate provides a very reliable operation over a wide temperature range. This transmitter and receiver pair enables the simple implementation of a data link at up to 4.8Kbit/s at distances up to 75 meters on building and 250 meters on open ground. These modules will suit one to one and multi node wireless links in application 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 application such as hand held terminals.
