Description
The R F Solutions Ltd. AM hybrid transmitter module provides a complete RF transmitter which can be used to transmit data at up to 4KHz from any standard CMOS/TTL source. The module is very simple to operate and offers low current consumption (typ. 4 mA). Data can be supplied directly from a microprocessor or encoding device, thus keeping the component count down and ensuring a low hardware cost. The module exhibits extremely stable electronic characteristics due to the use of ‘Thick-Film’ hybrid technology, which uses no adjustable components and ensures very reliable operation. The modules are compatible with R F solutions Ltd. range of AM receivers to provide a complete solution.
