pSemi Corp., formerly Peregrine Semiconductor, announces the expansion of its digital step attenuator (DSA) portfolio with a family of value, high performance DSAs. The four value DSAs feature industry-leading attenuation accuracy at an entry-level price point.
Volume-production quantities, samples and evaluation kits will be available in August.
The value DSA family — the PE43620, PE43650, PE43665 and PE43670 — encompass 2-, 5-, 6- or 7-bit configurations, including a 6-bit, 75 Ω product. These high performance DSAs have excellent attenuation accuracy, low insertion loss and high linearity. All four are available in compact QFN packages.

"pSemi has a long, successful history of digital step attenuator development. Our team introduced the world's first single-chip DSA in 2004 and, now, we are further expanding our DSA portfolio with the introduction of the value, high performance DSAs. These four new DSAs nicely round out our DSA portfolio and complement our RF catalog parts." — Jim Cable, CTO at pSemi
