The R.F. 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 incorporates either a SAW Filter and pre amplifier
front end or PLL Synthesizer for maximum sensitivity and reduced EMC emissions. These 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.
