Description
The RF Solutions AM Superheterodyne Receivers are compact modules, which can be used to capture
undecoded data from any equivalent AM Transmitter, such as R.F. Solutions AM-RT4 range of transmitters.
(See AM Transmitter datasheet).
Receivers are manufactured on a ceramic substrate, the RRS3 incorporates an LC Filter, pre amplifier front
end and PLL Synthesizer for high sensitivity and reduced EMC emissions. The RRQ5 incorporates a SAW
Filter to provide a further increase in the module sensitivity. The modules show a very high frequency
stability over a wide operating temperature even when subjected to mechanical vibrations or manual
handling offering a very cost effective solution.
