Programmable Attenuators
P-AT Series
I
Features
1.
Used for frequencies from DC to 26.5GHz (max.)
Input/output couplings utilizes Hirose’s HE*
connector, which is combination of the internal
attenuation elements, provides the required
attenuation characteristic.
2.Self-disconnecting
The drive current will automatically switch off after
setting the attenuation.
3.Automatic return
In the event of sudden shock the attenuation will
quickly return to the pre-set level.
I
Applications
Wide variety of measuring instruments and other
devices requiring control of high frequency
transmission lines.
* HE connector will mate with K type connectors
* K connector is a trademark of Anritsu Co.
