Overview:
Qorvo's CMD279C3 is a positive 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 CMD279C3 has a low insertion loss of 3.5 at 9 GHz and the attenuation accuracy is typically 0.2 dB step error. The CMD279C3 is a 50 ohm matched design which eliminates the need for RF port matching.
