RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection.

RF waveguide attenuators are used to reduce the power level of a signal by a certain amount (gain), with little or no reflections.

Delay lines are devices used to slow down a signal by a time interval in an electrical network.

PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers.

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters.
