Description

The G2 / SMG2 attenuator is a discrete hybrid

design,

which

uses

thin

film

manufacturing

processes for accurate performance and high

reliability.

The design used 3 pin diodes to provide a non linear

attenuation response across a broadband frequency

range. Both TO-8 and surface mount packages are

hermetically sealed. MIL-STD-883 environmental

screening is available.

* Restrictions on Hazardous Substances, European Union Directive 2011/65/EU.
