The 70TX-LM is a low-cost 10 mW FM narrow band multi-channel radio data transmitter according to EN 300220. The module is realized as a synthesizer and allows operation in the European ISM band from 433,100 to 434,700 MHz on a total of 8 channels without a fixed raster. The transmitter reaches its full power already at 2.3V.

The UHF mini transmitter 70TX-M1 is one of the smallest crystal stabilized transmitter modules in its class. A wide voltage range and its low power consumption combined with the small size makes the module ideal for portable and mobile applications. By the interesting combination of reliable technologies it was possible to design a product, putting together the advantages of frequency stable crystal oscillators and the synthesizer concept in a very small size The 70TX-M1 transmitter 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. 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.

The UHF mini transmitter 70TX-D is one of the smallest crystal stabilized transmitter modules in the 500mW class. A wide voltage range and its low power consumption combined with the small size makes the module ideal for portable and mobile applications.

The UHF power transmitter 70TX-D2 is the optimized follower of the reliable 70TX-D and was reduced in high about 25%. Probably it is now the smallest 500mW transmitter on the market. It`s the ideal solution for portable and mobile applications where the size is very important. By reducing the power consumption of the module the usable voltage range was adjusted upwards.
