These attenuators are designed to precisely reduce the amplitude or power of a signal without distorting its waveform. Their excellent return loss (low VSWR) makes them an ideal attenuator for head-end applications.

A high-pass filter is a combination of a capacitor, an inductor, and a resistor that pass a signal component above a certain frequency and greatly suppresses a signal component below the frequency. Its characteristics can be described by impulse response and frequency response in the time domain and frequency domain, respectively. The latter is a function representation of the frequency as an independent variable. In general, it is a complex variable with the complex variable jω as an independent variable, expressed as H(jω). Its mode H(ω) and the angle φ(ω) are functions of the angular frequency ω, which are called the “amplitude frequency response” and “phase frequency response” of the system, respectively, which represent the signal components of different frequencies in the excitation source. The amplitude and phase changes encountered by the system. It can be shown that the "frequency response" of the system is the Fourier transform of the "impact response" of the system. When a linear passive system can be represented by an N-order linear differential equation, the frequency response H(jω) is a rational fraction whose numerator and denominator correspond to the right and left sides of the differential equation, respectively.
