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.
