4-16GHz 6-bit digital attenuator

GaAs Monolithic Microwave IC

Description

The CHT4016-99F is a 4-16GHz 6-bit digital

attenuator designed to address a dynamic of

31.5dB by 0.5dB step.

It

is

designed

for

a

wide

range

of

applications, from military to commercial

communication systems.

The circuit is manufactured with a pHEMT

process, 0.25µm gate length, via holes

through

the

substrate,

air

bridges

and

electron beam gate lithography.

It is available in chip form.
