UltraCMOS® RF Digital Step Attenuators

pSemi UltraCMOS® RF Digital Step Attenuators (DSAs) offer flexibility and performance for wireless and broadband infrastructure equipment, LMRs, test-and-measurement equipment, and military RF applications. The UltraCMOS RF DSAs are offered in 50Ω and 75Ω variants, with multiple programming mode options, including serial, direct parallel, and latched parallel, making it easy to design them into a wide range of systems. These devices offer best-in-class linearity, outstanding attenuation accuracy, and low insertion loss.
