QAM-TX2-433 RF Solutions

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.
