FM-RRFQ1-868

FM TRANSMITTER & RECEIVER FM-RTFQ SERIES HYBRID MODULES. FM-RRFQ SERIES FM Radio Transmitter & Receivers Available as 315 or 433 or 868MHz Transmit Range up to 250m Miniature Packages Data Rate up to 9.6Kbps No Adjustable Components Very Stable Operating Frequency RTFQ1 RTFQ1 SM 0 Operates from 20 to +85 C Transmitter 3-12 Supply Voltage SIL, DIL or SMT Packages available Receiver RTFQ2 PLL XTAL Design CMOS/TTL Output RSSI Output Standby Mode (max 100nA) 5V Supply Voltage Applications RRFQ1 Wireless Security Systems Car Alarms Remote Gate Controls Remote Sensing Data Capture Sensor Reporting RRFQ2 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 processes on thick film ceramic substrates, the hybrid modules exhibit extremely stable electronic characteristics over an industrial temperature range. The hybrid technology uses no adjustable components ensuring very reliable operation. This transmitter and receiver pair enables the simple implementation of a data link at distances up to 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. DS069-8 Aug 07 2007 Reg. No. 227 4001, England Page 1 FM TRANSMITTER & RECEIVER FM-RTFQ SERIES HYBRID MODULES. FM-RRFQ SERIES Transmitters There are three 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. RTFQ1 SM: A dual in line surface mount package operating at 3.3V. This provides the quickest and most efficient mechanical fixing to the host PCB. Currently only available in 433MHz. RTFQ2 A Single in Line Package incorporating a voltage regulator for 3-12V operation. Compatible with many other RF transmitter module footprints available.
