Key Features
- Ultra wideband performance
- Low insertion loss
- Wide attenuation range
- Small die size
Qorvo's CMD282 is negative controlled, wideband GaAs MMIC 2-bit digital attenuator die which operates from DC to 40 GHz. Each bit of the attenuator is controlled by a single voltage of either 0 V or -5 V. The attenuator bit values are 4 dB and 8 dB, for a total attenuation of 12 dB. The CMD282 has a low insertion loss of 1.5 dB at 18 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD282 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD282 offers full passivation for increased reliability and moisture protection.
