FM SIL TRANSMITTER MODULE • • • • • • • • • • • • • • • • FM Radio Transmitter Transmit Range Up To 250m CMOS/TTL Input SIL Package No Adjustable Components Very Stable Operating Frequency Low Current Consumption (Typ 8mA) W ide Operating Voltage (2.7-14V) Available As 315, 418 Or 433MHz Compatible With RF Solutions FM Receivers FM-RTF3-XXX Applications W ireless Security Systems Car Alarms Remote Gate Controls Remote Sensing Data Capture Sensor Reporting Description The R F Solutions Ltd. FM hybrid transmitter module provides a complete RF transmitter which can be used to transmit data at up to 9.6KHz from any standard CMOS/TTL source. The module is very simple to operate and offers low current consumption (typ. 8mA). Data can be supplied directly from a microprocessor or encoding 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 modules are compatible with R F solutions Ltd. range of FM receivers to provide a complete solution. Circuit Schematic VCC External Antenna Data In DS059_2 Jul ‘01 ©2001 Reg.
