Description
L-com carries a wide range of fixed attenuators with a broad selection of attenuation levels and frequency ranges. RF fixed
attenuators lower the amplitude of a signal (attenuate) by specific amount and can be used in a wide variety of applications.
These attenuators are used when signal levels need to be reduced to protect measurement equipment or other circuitry, to
extend the range of power meters and amplifiers, and to impedance match circuits by reducing the VSWR seen by adjacent
components. RF attenuators can prevent signal overload in amplifiers, receivers and detectors, adjusting the signal level to
optimal power range.
Few RF components are as commonly used as fixed coaxial attenuators, and L-com carries one of the largest in-stock variet-
ies and ships them same day. The 18 dB Fixed Attenuator LCAT1000-18 is rated to 2 Watts and operates from DC to 6 GHz.
The versatile coaxial package uses SMA male to SMA female connectors and is also RoHS compliant.
