SA18L-40
DATA SHEET
40 dB Fixed Attenuator SMA Male To SMA Female
Up To 18 GHz Rated To 2 Watts With Passivated
Stainless Steel Body
Fairview Microwave carries a broad selection of fixed attenuators with a wide
range of attenuation levels, frequency ranges, and power dissipation ranges. Also
known as RF pads, RF microwave attenuators lower the amplitude of a signal
(or attenuate) a known amount. These attenuator pads can be used in a wide
variety of applications including reducing a signal level to protect measurement
equipment or other circuitry, extending the range of power meters and amplifiers,
and impedance matching 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 a range that is optimal.
Few RF components are as commonly used as fixed coaxial attenuators, and
Fairview Microwave carries one of the largest in-stock selections and ships them
same day. The SA18L-40 is a 40 dB Fixed Attenuator that operates from DC to 18
GHz and is rated to 2 Watts. The versatile coaxial package uses SMA male to SMA
female connectors and is also REACH and RoHS compliant.
