P-AT-6(8-70)A pdf
Programmable Attenuators
P-AT Series
sProduct Specifications
sFeatures
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.
sApplications
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.
Ratings Frequency range
DC~8GHz(P-AT-6,AP-AT-7) Operating temperate range -10ç to +75ç(No freezing)
DC~26.5GHz(P-AT-8) Operating relative humidity
95% Max.
Characteristic
