UHF-FM PLL Power-Transmitter 70TX-D

      

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.
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-D 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 434,775 MHz.
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 very long distance communication at simplex or half-duplex. Together with our remote control unit FSM24 you can reach 4500 m and more at free sight.
