    FMUSER 5W UHF/VHF TV Transmitter

    General Description
     This FMUSER transmitter makes use of RF modulation technology and imported power amplifier, featuring simple circuit design, good performance, stable operation and long time continuously running. It can make up a medium-power TV station when connected with the microwave equipment, satellite TV receiving equipment and video recording equipment.
     
     
    The complete kit contains:
    1. 5W TV Transmitter                  one Set 
    3. Video input cable                    one Piece
    4. Audio input cable                    one Piece
    5. Power supply cord                  one Piece
    6. Operation instructions             one Copy
     
     
     
     
     
     
     
     
    Operation Principle
     
     The 5W TV transmitter is composed of three parts, a modulation unit, a power amplifier (PA) unit and a switching power supply. In the modulation unit, video signals are adjusted to the suitable modulation depth via a level adjusting potentiometer and then clamped by a diode. The audio signals are sent to a FM oscillator for frequency modulating after its frequency deviation is adjusted by the level potentiometer. The FM oscillator employs a LC oscillator and generates6.5MHz FM signal by a variable capacitance diode. The frequency of the crystal oscillator is multiplied to generate the wanted visual carrier. 6.5MHz FM signal and video signal modulate the visual carrier simultaneously. A bandpass filter will filter out unwanted components and the signals will be sent to the PA unit by a broadband amplifier.
     PA unit is composed of first stage PA and final stage PA units. The first stage PA unit consists of a module and a transistor and adopts a class-A broadband amplifier. The gain of the module is 34dB and the total gain of the PA is about 54dB. Working current of the triode transistor can be calculated by measuring voltages on both ends of the resistor R6 (2W 1W).
     The power supply unit contains a switching power supply which features small size, lighter weight and high efficiency and can provide over-current and short-circuit protections, so that the transmitter will work at a stable 28V DC voltage. The overall equipment uses one 28V/10A power supplies. In the case of one of the power supplies is out of order, the transmitter will be switched off into safety mode automatically.

    How far(long) the transmitter cover?

    The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

    EXAMPLE 5W FM Transmitter use in the city and hometown:

    I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

    I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

    I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

    Below are the approximate range of different power FM Transmitters. ( The range is diameter )

    0.1W ~ 5W FM Transmitter :100M ~1KM

    5W ~15W FM Ttransmitter : 1KM ~ 3KM

    15W ~ 80W FM Transmitter : 3KM ~10KM

    80W ~500W FM Transmitter : 10KM ~30KM

    500W ~1000W FM Transmitter : 30KM ~ 50KM

    1KW ~ 2KW FM Transmitter : 50KM ~100KM

    2KW ~5KW FM Transmitter : 100KM ~150KM

    5KW ~10KW FM Transmitter : 150KM ~200KM
