DC-22 GHz (L, S, C, X, Ku, K Band) 2-bit Digital Attenuator

The CMD282C3 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 4 dB and 8 dB, for a total attenuation of 12 dB. The CMD282C3 has a low insertion loss of 1.9 dB at 10 GHz and the attenuation accuracy is typically 0.2 dB step error. The CMD282C3 is a 50 ohm matched design which eliminates the need for RF port matching.

Custom MMIC Space Qualified MIMCs
Space Qualification

Custom MMIC strives to design all our MMIC devices in a manner such that they can be readily chosen for your space applications. We offer turnkey space screening / testing service when a device is categorized as "Ready for Space Screening" on our website. In some cases, our devices have already been "Space Qualified" or "Mission Specific" and are often available from stock. Our "Mission Specific" devices are screened based on custom applications where screening is derived from MIL requirements and tailored specific to customer needs. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
