Attenuators

An attenuator is an electronic device that reduces the magnitude of an electrical signal without introducing distortion. It is most commonly used to reduce the peak power of high-power radio or microwave signals so as to improve signal-to-noise ratio. A typical attenuator looks like a resistor and is made up of attenuation elements, which may take the form of diode, varactor, and semiconductor switches, depending on the application.

Working principle

The working principle of PE43404MLI is based on a resistive type attenuator. It is made of four high performance resistive attenuation elements which are connected in series. The four elements are spaced at exact intervals to achieve both high linearity and sharp cut-off at desired frequencies. The attenuation factor of the unit is determined by the relative resistance values of each discrete element. The resistance values are set in accordance with an attenuation slope requirement, which defines the frequency points where the gain should drop and how much gain should be drop at each frequency point.

The attenuation range of PE43404MLI is from 0dB to 20dB, and the maximum input power is typically +21dBm, and the maximum output power is +1dBm. In addition, the unit has high linearity, excellent temperature stability and good return loss. Furthermore, the small size of this attenuator makes it well suited for integration in a variety of components.

PE43404MLI is an ideal solution for applications that require accuracy, repeatability, and small size. It provides a robust and reliable performance with superior accuracy and temperature stability. In summary, the PE43404MLI is a robust, low-cost attenuator family that offers excellent performance for a wide range of radio frequency applications.
