AM TRANSMITTER MODULE QAM-TX3 Features • Complete RF Transmitter • SAW Resonator • Transmit Range Up To 50m • CMOS / TTL Input • No Adjustable Components • Stable Operating Frequency • Wide Operating Voltage (3-12v) • ASK Modulation • Available as 315 or 433 MHz Applications • Wireless Security Systems • Garage Door controller • Remote Gate Controls • Remote Sensing • Data Capture • Sensor Reporting Description The Quasar UK AM hybrid transmitter module provides a complete RF transmitter which can be used to transmit data at up to 3KHz from any standard CMOS/TTL source. The module is very simple to operate and offers a wide operating voltage range, the RF Power output increases in line with the voltage level applied to the module. Data can be supplied directly from a microprocessor or encoding device, thus keeping the component count down and ensuring a low hardware cost. The modules are compatible with the Quasar UK Ltd. range of AM receivers to provide a complete solution. Typical Application For further information on this circuit please refer to the RF Solutions datasheet DS600.
