Features

• WIDE BAND PERFORMANCE

• EXCELLENT INSERTION LOSS: < 3.0 dB (TYP.)

• HIGH DYNAMIC RANGE: 30 dB TO 3000 MHz (TYP.)

Description

The G40 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.
