Narrow band single channel receiver 70RX-MP2

The 70RX-M2 is a high quality narrow band FM single channel radio receiver according to EN300220 and Part 15B with improved blocking behaviour. This significantly increases the immunity to interference from out-of-band interferers. In combination with our transmitter modules, radio systems with a very long range can be set up in simplex or half duplex operation.

The receiver is produced by default for the European ISM band at 433 / 434 MHz. We offer all available 139 channels from 433.0625 - 434.7875 MHz in a 12.5 kHz raster. The module is available for most of the worldwide used frequency bands in the 400 MHz range: 406 - 418 MHz, 418 - 428 MHz, 428 - 438 MHz, 438 - 448 MHz, 456 - 466 MHz and 466 - 476 MHz. Due to the wide range of our filters, very few variants are sufficient.

Optionally, frequencies in the range of 250 to 550 MHz are also possible. Please ask us for your desired frequency. If required, our service can re-program the frequency of the module at a later date without hardware changes in a range of up to +-3 MHz.

The signals Mute and RSSI are available for evaluating the reception quality. Determining the optimum reception place for stationary use is very easy.

The excellent RF sensitivity allows signal transmissions over very long distances. 10mW output power of 70TX-M1 or 70TX-S together with the remote control unit FSM24 is f.e. sufficient for a free field range of more than 2000 m. The receiver is also characterized by a very high selectivity, which allows the operation of many devices at the same place.

The direct audio signal output doesn`t restrict its use for any kind of coding. Any type of recommendable signal can be used, even analogue audio signals, e.g. speech. A Butterworth filter at the output eliminates noise- and interfering signals with high efficiency.
