GENERAL INFORMATION
The KDI/Triangle 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.
