Description
The Quasar UK AM hybrid receiver module provides a complete Radio receiver which can be used to
receive undecoded data from the range of Quasar (UK) transmitter modules.
The module is very simple to operate and offers a low current consumption, allowing for extended
battery life when used in mobile applications.
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.
