UHF-FM Synthesized-Transmitter 70 TX-S

      

The synthesizer controlled FM mini transmitter 70TX-S is a high end solution with an excellent performance / price relation in its class. The extremely small sized module is completely conform to EN 300220. A wide voltage range and its low power consumption combined with the small size makes the module ideal for portable and mobile applications.
Availlable for a wide frequency range, primarely for the european ISM band from 433,05 to 434,79 MHz, the modul allows an operation on 139 radio channels, each 12,5 kHz apart. The module is also available for the frequency range from 410 to 510 MHz.
The internal microcontroller converts an external 8 bit wide information into a serial data stream for the synthesizer frequency adjustment. No complicate programming is necessary.
The integrated standby function allows a very short startup time if needed.
The combination with our receiver-modules 70RX-M1 or 70RX-S1 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.
