AM TRANSMITTER MODULE QAM-TX2 Features • Complete RF Transmitter • Transmit Range Up To 50m • CMOS / TTL Input • No Adjustable Components • Very Stable Operating Frequency • Low Current Consumption (Typ 11mA) • Wide Operating Voltage (3-12v) • ASK Modulation • Available as 315 or 433 MHz Applications • Wireless Security Systems • Car Alarms • 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 low current consumption (typ. 12mA @5V). 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.
