Description
The G30 attenuator is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance and
high reliability.
This design uses three pin diodes to provide a non linear
attenuation response across a broadband frequency range.
Both TO-8 and Surface Mount packages are hermetically sealed,
and MIL-STD-883 environmental screening is available.
