| AM SUPERHETRODYNE RECEIVERS. * * * * * * * * * * * * Compact Hybrid Module. Ceramic Substrate 315 / 433 / 868MHz Available Very High Frequency Stability Receiving Range Up To 100 Metres. CMOS/TTL Compatible Output. Single Supply Voltage 5V. Operates from -25 - +85o C Compatible With R.F. Solutions AM Transmitters. Compliant to ETS300-220 RRQ3 * Sensitivity Typ -107dbm * PLL Synthesizer Front End * Sleep Mode AM-RRS3-XXX AM-RRQ3-XXX RRS3 Sensitivity Typ -106dbm Saw Filter Front End. 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.
