Coaxial terminators are electrical devices that connect to the ends of coaxial cables to prevent signals from reflecting back when they reach the end of the cable.
Electrical terminators are installed at the end of a bus or transmission line to prevent signals from reflecting back. Sometimes called electrical terminators, these devices are used to prevent electrical interference.
RF 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).
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters.
