Features

• FAST SWITCHING: < 0.2 µsec, 10 TO 90% (TYP.)

< 1 µsec, 0 TO 100% (TYP.)

• HIGH DYNAMIC RANGE: 40 dB TO 1000 MHz (TYP.)

• LOW VSWR: 1.4:1 (TYP.)

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.
