Rotary Attenuators (SMA Type)
M-AT Series
Space-saving Design (Miniature and Lightweight)
15.0 mm
(0.59 inches)
ꢀOverview
High reliability rotary attenuator for adjusting the signal
level in variety of high frequency devices.
ꢀFeatures
01. Ease of mounting in high-density applications
Small size and light weight allows side-by-side panel
mounting of several attenuators.
02. Supports a frequency range from DC to 3GHz
Used over a wide bandwidth with usable frequencies from
DC to 3GHz.
03. Easy connection
The output / input connectors (SMA jacks) face back,
allowing connection/disconnection after the attenuator
has been mounted to the panel.
04. Two attenuation directions.
Standard M-AT-1L attenuators are offered as clockwise
or counter-clockwise types.
05. Availability of custom requirements
Attenuators can be modified to fit specific requirements
(Example: attenuation steps, connector type )
Contact nearest Hirose Electric sales representative for
details.
ꢀApplication
W-CDMA base stations and a wide variety of high
frequency devices.
