UHF-FM Synth. Power Transmitter 70TX-E1

(Preliminary)

The UHF power transmitter 70TX-E1 is the optimized follower of the reliable 70TX-E and was reduced in volume about 50%. Probably it is now the smallest 500mW transmitter with synthesizer technologie 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 complete new concept combines the advantages of the DDS with the well known synthesizer. The modulation of the RF-signal can now be done analog as usual or directly digital. The integrated ARM7 processor executes all needed routines of digitizing of the signal with high resolution in real time. Afore a butterworth filter of up to 8th order cleans the signal from unwanted frequency components that are not necessary for a efficient use of the channel.

The 70TX-E1 transmitter has a startup time that is well below the old module and should be sufficient for nearly all applications without a standby function. On the other hand there are two standby modes that allow a much faster startup behaviour (e.g. for TDMA use) or can help to reduce the hardware costs on the pcb of the user.

The combination with our receiver-modules 70RX-M2 or 70RX-S2 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 5000m and more at free sight.
