AM Receiver 433 MHZ 3V – High Sensitivity
Miniature AM superheterodyne receiver with high input sensitivity and high immunity to interfering electromagnetic fields
SKU 8110-RX-4MM3/FEAN 8219671121750Item type: AssembledRF receivers
Description
Miniaturized AM superheterodyne receiver with high input sensitivity and high immunity to interfering electromagnetic fields. It features a digital output filter capable of suppressing short pulses (shorter than 150 usec) that may be present in the received signal (due to strong disturbances caused by brushed motors), thereby restoring pulse integrity and allowing the receiving system to operate correctly. Suitable for applications where disturbances are present, such as gate opening controls and particularly noisy industrial environments.
Technical specifications
- Interference rejection at ±10 MHz: 60 dB
