Attenuators

Attenuators are devices used to reduce an input signal, generally by causing signal degradation or distortion. They are commonly used in radio transmission and audio systems. The M3933/16-34N attenuator is a mobile two-band device with wide application fields.

The M3933/16-34N device uses five different antenna elements: two ones for the 1620 kHz band (short and long), two ones for the 3420 kHz band (short and long) and one omnidirectional antenna. For each of the two main bands, a wide operating frequency range is available. The operation is made with no external amplifier, provided that the input signal strength is sufficient for the desired output.

The function of the M3933/16-34N attenuator is to reduce the signal strength from an incoming signal source, such as a radio transmission system. The device is connected to the signal source, and by setting appropriate attenuation the device reduces the signal level before it reaches the amplifier or other connected device. The amount of attenuation is usually adjustable. The reduction in signal level can be used to compensate for mismatching of devices, reduce distortion and noise, or even protect against overload.

In mobile applications, the M3933/16-34N attenuator can be used to reduce the signal level of a high signal level compared to a low signal level (Fig.1). In a broadcast tower, the device can be employed in order to reduce the transmitted signal strength to the correct level for wider area coverage. It can also be used in applications such as TV broadcasting, where it is desired to reduce the field strength to avoid overloading the TV receivers. In addition, the device can be used for antenna control, to maintain a certain level of signal strength, or in laboratory or commercial communication systems, where signal strength must be controlled.

The operation of the M3933/16-34N attenuator is based on a chain of RF amplifiers connected in series, with each amplifier having a certain attenuation level depending on its settings. The attenuator is powered directly from the signal source, and all the components are in the same state of ON or OFF. In mobile applications, the device can operate in an adjustable mode, in which the signal level for each band can be set independently. The device is also available in fixed modes, where the signal level for each band is pre-set.

In summary, the M3933/16-34N attenuator is a very versatile device, with a wide range of applications. It can be used to reduce radio frequency signals, or to provide a constant, uniform signal level across different transmitters. It is designed for mobile and stationary applications, and can provide a wide range of attenuation levels. The device is easy to install and use, and is suitable for a wide variety of tasks in radio communication and audio systems.
