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.
