The 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.

In addition to offering delivery from stock on our own evaluation boards for nearly all our die and packaged devices, Custom MMIC has also put nearly 30% of our devices into the X-Microwave block system. This drop-in simulation, prototyping, and production system enables efficient and expedient microwave and millimeter-wave circuit development and testing.
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" and are often available from stock. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
