Qorvo's CMD281C3 is a negative controlled, wideband GaAs MMIC 2-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 2 dB and 4 dB, for a total attenuation of 6 dB. The CMD281C3 has a low insertion loss of 1.5 dB at 10 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD281C3 is a 50 ohm matched design which eliminates the need for RF port matching.

X-Microwave Design System
This product is available as an X-Microwave Block (X-MWblock) for evaluation.
X-MWblocks are RF and microwave "drop-in" components that can be used individually for prototyping or in production assemblies. X-MWblocks are easy to test, integrate, align, and configure to 60 GHz and beyond. No messy sweat soldering or silver epoxy processes are required. X-MWblocks are highly characterized with S-parameter models and connect with a patented solder-less interconnect technology.
