Product Overview

The CMD285C3 is DC to 20 GHz GaAs MMIC absorptive

Voltage Variable Attenuator (VVA) housed in a leadless

surface mount package ideally suited for military, space

and communications systems. The VVA uses two analog

control voltages varied between -5 V and 0 V to control RF

signal levels over a 35 dB dynamic range. The CMD285C3

has a low insertion loss of 3.2 dB at 10 GHz and is a 50

ohm matched design, eliminating the need for RF port

matching.

Key Features

• Wideband Performance

• Low Insertion Loss

• Wide Attenuation Range

• High Linearity

• Pb-Free RoHs Compliant 3x3 mm SMT Package
