CHT4012-QDG

RoHS COMPLIANT

DC-6GHz 6-BIT DIGITAL ATTENUATOR

GaAs Monolithic Microwave IC in SMD leadless package

Description

The CHT4012-QDG is a DC-6GHz monolithic

6-bit digital attenuator with a LSB = 0.5dB

offering a high dynamic range and a high

accuracy, the RMS amplitude error is

typically as low as 0.3dB. The circuit provides

low insertion loss 2.5dB associated to input

and output return losses better than 13dB. A

CMOS and TTL compatible interface is

available on chip.

It is designed for

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.
