250-25RM-S

Attenuators are devices used to adjust the signal power to a desired level. The 250-25RM-S attenuator is a low-power, high-performance attenuator designed to reduce a signal power over a wide operating temperature range. This attenuator is composed of four signal lines and features a built-in temperature compensation function.

The 250-25RM-S attenuator is mainly used for low-power signal attenuation in the 0-25 dB range, such as in military frequencies, telecommunications and electronic instrumentation. It is also suitable for other applications where a wide frequency range is required. For example, in fiber-optic systems where an adjustment of signal intensity is required, the 250-25RM-S can be used to reduce the signal-to-noise ratio.

The operating principle of the 250-25RM-S attenuator is based on attenuation of an input signal by controlled impedance matching. This impedance matching is created by the use of low-loss RF resistors, which control the power output of the signal. The resistors are sized according to the desired value of attenuation, taking into consideration the frequency, input power, and environment. The resistors must also be designed for low loss, so as to reduce signal distortion.

The 250-25RM-S attenuator is a flat-top, low-power attenuator that is highly stable which makes it suitable for use in harsh and extreme environments. Some of its features include a wide operating temperature range (0-70 degrees Celsius), resistance tolerance of ± 0.2%, and a very low insertion loss (0.2 dB maximum). Additionally, the attenuator is tested in accordance with MIL-STD-675 for dependability and performance.

In summary, the 250-25RM-S attenuator is a low-power, high-performance attenuator designed for use in the 0-25 dB range. It is composed of four signal lines and features a built-in temperature compensation function. The operating principle of the 250-25RM-S is based on attenuation of an input signal by controlled impedance matching. The attenuator is highly stable and has a wide operating temperature range, resistance tolerance of ± 0.2%, and a very low insertion loss (0.2 dB maximum).
