M3933/25-25S

Attenuators are electrical components used to reduce the level of a signal without significantly transforming other parameters of the signal. M3933/25-25S is a type of network attenuator.

The M3933/25-25S is made of 25 watt resistors in series-parallel. It consists of 16 resistors (8 + and 8 -) of twp different values. The total attenuation over a range of 10 MHz to 1 GHz is 25 dB with ±0.75 dB accuracy. The maximum power handling capacity of this attenuator is 25 Watts peak power.

The M3933/25-25S integrates a high isolation voltage of 1000Vrms for 1 minute, and high potential insulation resistance of 100 MOhms. It provides excellent frequency response due to its parallel connection of resistors that prevents from overpowering the device. The device is also designed for attenuation of 10 dB – 90 dB with ±1.0 dB accuracy and high stability over temperature.

The M3933/25-25S applications includes radio and communication applications, and is typically used for amplitude linearization, signal triggering , and as a power attenuator.

The M3933/25-25S working principle is based on the fact that its resistors are connected in parallel-series connection. Thus, the device is able to provide a higher level of power attenuation in comparison with a single resistor. The combination of resistors reduces the output signal level and ensures better signal integrity and better noise immunity. Moreover, the parallel-series configuration helps to maintain the signal integrity and performance at higher frequencies.

In addition, the M3933/25-25S attenuator is easy to use and can be installed in just a few steps. The attenuator is equipped with a BNC connector and can be connected with other equipment to decrease the signal level. In order to use the attenuator, a voltage source of 25V or less should be connected to the BNC connector.

In conclusion, the M3933/25-25S is a network attenuator that is designed primarily for radio and communication applications. The device is composed of 16 resistors connected in a series-parallel configuration, allowing it to provide a higher level of power attenuation and signal stability. The unique combination of resistors ensures the excellent frequency response and performance of the device. In addition, the attenuator is easy to use and is connected with other equipment via a BNC connector.
