CMD280C3 - DC-18 GHz 5-bit Digital Attenuator

General Description

The CMD280C3 is a negative controlled, wideband GaAs MMIC 5-bit digital attenuator housed in a leadless 3x3 mm surface mount package.

Each bit of the attenuator is controlled by a single voltage of either 0 V or -5 V.

Key Features

Wideband performance.
Low insertion loss.
Wide attenuation range.
Pb-free RoHs compliant 3x3 QFN package.

CMD280C3 DC-18 GHz 5-bit Digital Attenuator Features ► Wideband performance ► Low insertion loss ► Wide attenuation range ► Pb-free RoHs compliant 3x3 QFN package Description The CMD280C3 is a negative controlled, wideband GaAs MMIC 5-bit digital attenuator housed in a leadless 3x3 mm surface mount package. Each bit of the attenuator is controlled by a single voltage of either 0 V or -5 V. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB, for a total attenuation of 15.5 dB. The CMD280C3 has a low insertion loss of 3 at 10 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD280C3 is a 50 ohm matched design which eliminates the need for RF port matching.
