JRC CCB-555 ATT CIRCUIT Attenuation RF Assembly E6393-61005

JRC / Agilent ATT CIRCUIT RF Assembly. JRC P/N CCB-555, Agilent P/N E6393-61005. This may be a variable attenuator assembly, I am not certain. 

Please note: this has a very strong off-gassing smell. It could be a conformal coating or the PC board phenol. Just be prepared when opening the static bag.
