FM SUPER HETERODYNE RECEIVER QFM-RX1 Features • • • • • • FSK Radio Receiver CMOS / TTL Output Stable Operating Frequency 5Vdc Operating Voltage Low Power Consumption Wide Operating temperature Applications • • • • • • Car Security Systems Automation Systems Remote Gate Controls Remote Sensing Data Capture Sensor Reporting Description The Quasar UK FM-RX1 Super Heterodyne receiver module provides a complete radio receiver which can be used to receive undecoded data from the range of Quasar (UK) FM transmitter modules. The receiver incorporates an entire Phase-Locked Loop (PLL) ensuring precise local oscillator generation. The module is very simple to operate and offers low power consumption allowing for extended battery life without the need to power down the module. Data can be fed directly into a microprocessor or decoding device, thus keeping the component count down and ensuring a low hardware cost. All receivers are compatible, producing a CMOS/TTL output, and only require connections to power and antenna.
