250w Dc 2ghz Rf Attenuator

Some pictures of a new started project of a 250W attenuator. I decided to build this because I will need it to be able to test the 2C39 23cm amplifier.

The attenuator is from Barry industries A3000-250-4X. A fan cooled heat-sink is connected to a copper plate.

Wiring and shielding is left to be done.
