MACOM Announces Industry’s First DC-40 GHz, 6-bit Digital Attenuator

M/A-COM Technology Solutions Inc. (“MACOM”), a leading supplier of high performance RF, microwave, and millimeter wave products, today announced a new wideband 6-bit digital attenuator which is ideal for broadband applications, such as military radar and radio systems, test equipment, and commercial microwave radio and satellite links.

The digital attenuator is offered as both bare DIE, MAAD-011021-DIE, and in a 3mm PQFN package, MAAD-011021, and operates from DC-40GHz and DC-30 GHz respectively. The 6-bit digital attenuator provides up to 31.5 dB of attenuation in 0.5 dB steps with attenuation error typically less than +/- 0.5 dB and industry leading phase accuracy of 4 degrees RMS error at 20 GHz. The digital attenuator integrates TTL digital control and is fully matched across the bandwidth of operation which enables the customer simple and fast implementation.

“The new digital attenuator offers the industry’s widest bandwidth 6-bit digital attenuator with the lowest phase variation performance available,” said Paul Beasly, Product Manager. “In combination with the 3mm PQFN option, the product offers customers a high frequency, small size, digital attenuator solution for applications that demand the greatest accuracy performance.”

The table below outlines typical performance:
