CATV Attenuator/Filter

CATV attenuators are circuits that reduce the power level of a signal by a certain amount (gain) with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB). There are two basic types of RF attenuators: fixed and variable. Filter consist of HPF, LPF, BPF & BRF. Here we are mainly provided high pass filter. HPF pass signals from high frequencies and reject signals from low frequencies. For high pass filters, the specified frequency is the cut-on frequency. Bandwidth is the range of frequencies that high pass filters pass with minimal attenuation. Ripple is the peak-to-peak variation of the passband response. Insertion loss is the total RF power transmission loss resulting from the insertion of a device in a transmission line. Insertion loss is the ratio of signal power at the output of the inserted device to the signal power at its input.
