SA18N50W-30
DATA SHEET
30 dB Fixed Attenuator N Male To N Female Up To
18 GHz Rated To 50 Watts With Black Aluminum
Heatsink 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 varieties and ships them
same day. The SA18N50W-30 is a 30 dB Fixed Attenuator that operates from
DC to 18 GHz and is rated to 50 Watts. The versatile coaxial package uses type
N male to type N female connectors and is also REACH and RoHS compliant.
The Black Anodized Aluminum Heatsink body allows for efficient heat dissipation
under high power usage conditions.
