HIGH POWER ATTENUATORS DC-12.4 GHz, UP TO 200 WATTS FEATURES: Flange Mounted or Chip * 10 to 200 Watts *1to 20 dB 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 200 watts of R.F. power. The PPA Model 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 ex- SERIES PPA, PAC PPA-20 outline 20 watts fem SIS, PPA-50 outline 50 watts - 975 __ > 108 rc +| 060 eo ceed 100C under rated power conditions. f _ .
