Boasting more than 35 million units shipped since its introduction, the PE4312 is a next-generation UltraCMOS DSA from Peregrine Semiconductor. The PE4312 enables flexible, wide dynamic-range network-infrastructure designs that require highly accurate and efficient amplitude control. 

This DSA upgrade is ideally suited for wireless-infrastructure devices, broadband consumer and infrastructure equipment, land mobile radios (LMRs), test-and-measurement equipment and military RF applications.

“Peregrine created the category of digital step attenuators with the UltraCMOS PE4302, and today’s announcement of our next-generation DSA will enable us to preserve our market leadership as the DSA category demands evolve,” says Kinana Hussain, senior marketing manager at Peregrine. “Based on customer requests, the UltraCMOS PE4312 features an extended temperature range that enable RF engineers to simplify thermal design, wider power-supply range to enable flexible power-supply routing, 1.8 V-compatible control voltage levels to enable lower-power designs and higher ESD ratings to ease manufacturing flow.”
