CMD279 - 2-30 GHz 5-bit Digital Attenuator

General Description

The CMD279 is positive controlled, wideband GaAs MMIC 5-bit digital attenuator die which operates from 2 to 30 GHz.

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.

Key Features

Ultra wideband performance.
Low insertion loss.
Wide attenuation range.
Small die size.

CMD279 2-30 GHz 5-bit Digital Attenuator Features ► Ultra wideband performance ► Low insertion loss ► Wide attenuation range ► Small die size Description The CMD279 is positive controlled, wideband GaAs MMIC 5-bit digital attenuator die which operates from 2 to 30 GHz. 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 CMD279 has a low insertion loss of 3.5 at 10 GHz and the attenuation accuracy is typically 0.2 dB step error. The CMD279 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD279 offers full passivation for increased reliability and moisture protection. Functional Block Diagram 234567 Vdd P0 P1 P2 P3 P4 0.
