| FM SIL RECEIVER MODULE * * * * * * * * * * Compact Hybrid Module Very High Frequency Stability (With No Adjustable Components). Receiving Range up to 250 Metres. CMOS/TTL Compatible Output. Low Current Consumption (Typ 5.5mA) Single Supply Voltage 5V. Compatible with R.F. Solutions FM Transmitters. Available as 315, or 433MHz Compliant To ETSI 300-220. Requires No Radio Licence to Operate. FM-RRF1 Description The R F Solutions Ltd. FM hybrid receiver module provides a complete RF receiver which can be used to receive data at up to 9.6Kbps. The module is very simple to operate and offers low current consumption (typ. 5.5 mA). The TTL/CMOS data output can be interfaced directly to a microprocessor or decoding device, thus keeping the component count down and ensuring a low hardware cost. The module exhibits extremely stable electronic characteristics due to the use of `Thick-Film' hybrid technology, which uses no adjustable components and ensures very reliable operation. The module is compatible with R F solutions Ltd. range of FM transmitters to provide a complete solution.
