The Aeroflex/KDI PPA Series of attenuators utilize a Beryllium
Oxide chip and thin film technology to provide devices which
can dissipate up to 100 watts of R.F. power. The PPA series
must be thermally bonded to a heat sink, using the mounting
holes provided, in order to operate within the temperature
rating indicated. The flange temperatures must not exceed
100°C under rated power conditions.
ORDERING INFORMATION
The Power Attenuators listed are available in 1 dB increments
from 1 thru 20 dB. Specify by selecting any of the series listed
and add the attenuation value desired to the basic series
designation. (See note 3)
