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.
