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.

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 UHF receiver was designed as follover of the reliable for all discerning applications of the wireless data- and analog signal communication and beats him in nearly all items. At the same time the case becomes and the input voltage range was expanded.

The new designed FM-receiver module 70RX-S1 from HM-Funktechnik is a high end receiver with internal synthesizer and microcontroller to convert the external 8 bit wide channel information into the serial data protocol for the synthesizer chip. No complicate programming is needed. The module offers 139 channels in the european 70cm ISM frequency range from 433,05 to 434,79 MHz and corresponds to EN 300220 demands.

The 70RX-SP2 is a high quality narrow band FM multi channel radio receiver according to EN 300220 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 70TRX-T1 is a professional 10mW narrow band multi channel transceiver according to EN 300220 or EN 300113. Compared to its predecessor 70TRX-T, the volume was reduced by 35%. Regarding to footprint and connecting the new module is 100% compatible.

The new designed FM-transceiver module 70TRX-T from HM-Funktechnik is an absolut high end module with internal synthesizer and microcontroller to convert the external 8 bit wide channel information into the serial data protocol for the synthesizer chip. No complicate programming is needed. The module offers 139 channels in the european 70cm ISM frequency range from 433.05 to 434.79 MHz and corresponds to EN 300220 demands.
