SERIES PPA

ATTENUATORS

High Power – DC-4GHz

RoHS

ꢀ

The Aeroflex/KDI PPA Series of attenuators utilize a Beryllium

Oxide chip and thin film technology to provide devices which

can dissipate up to 1ꢀꢀ 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

1ꢀꢀ°C under rated power conditions.
