Attenuator

An attenuator is a passive device for precise signal strength control, utilizing resistive networks or thin-film circuits to achieve calibrated energy loss. Its structure includes π/T-type networks, ceramic substrates, and shielded enclosures, offering fixed (3dB/10dB) or variable (0-60dB adjustable) attenuation with broadband performance (DC-40GHz), low VSWR (≤1.5), and high power handling (up to 100W). Essential in communication systems, test equipment, and radar for signal level adjustment, impedance matching, and system protection.
