Receiver 70RX-M1

The UHF-receiver 70RX-M1 was designed as a high-end receiver for ambitious applications in the wireless data and signal transmission generally. The sophisticated solution is realized by consequently used SMD-technology.

The 70RX-M1 receiver is a single channel, crystal stabilized solution, available for the frequency range from 410 to 510 MHz, mainly in the european 70cm ISM band from 433,100 to 434,75 MHz. Numerous national licences are available.

The module has a remarkable selectivity, which allows its use in applications where several modules must be operated locally and on adjacent radio channels at the same time.

The excellent RF sensitivity of –121dBm by CCITT weighting offers a long distance signal transmission.

The direct audio signal output doesn`t restrict its use for any kind of coding. Any type of recommendable signal can be used, even direct audio signals, e.g. speech.

The combination with our transmitter-modules 70TX-M1 or 70TX-S offers the user a perfect radio system with long distance communication at simplex or half-duplex. Together with our remote control unit FSM24 you can reach 2000 m and more at free sight.
