DESCRIPTION
The R.F. Solutions AM Superheterodyne Receiver module offers a compact modular RF
receiver, 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
data sheet).
The receiver is manufactured on a ceramic substrate incorporates a SAW Filter and pre
amplifier front end 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.
