Description
The R.F. Solutions range of AM ‘Super Regen’ Receiver modules are compact hybrid RF receivers, which
can be used to capture undecoded data from any AM Transmitter, such as R.F. Solutions AM-RT4 / 5
range of transmitters. (See AM Transmitter datasheet DS013).
These modules show a very high frequency stability over a wide operating temperature even when
subjected to mechanical vibrations or manual handling. A unique laser trimming process which has been
patented gives a very accurate on board inductor, removing the need for any adjustable components.
All receivers are compatible, producing a CMOS/TTL output, and require connections to power and
antenna only. The HRR6 is a version with Very Low Current consumption which has a typical quiescent
current drain of only 0.5mA. In addition the HRR8 operates from a 3Vdc supply.
RF Solutions also offer a range of Super Heterodyne Receivers, for data on these products (please see
Datasheet DS017).
