pSemi Expands Digital Step Attenuator (DSA) Portfolio with Family of Value, High-Performance DSAs

The Four DSAs Feature Industry-leading Attenuation Accuracy at an Entry-level Price Point   

PHILADELPHIA – INTERNATIONAL MICROWAVE SYMPOSIUM (IMS) – June 12, 2018 – In IMS Booth #1349, pSemiTM Corporation (formerly Peregrine Semiconductor), a Murata company focused on semiconductor integration, 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. 

“pSemi has a long, successful history of digital step attenuator development,” says Jim Cable, CTO at pSemi. “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.”  

pSemi Value DSAs

The value DSA family—the PE43620, PE43650PE43665 and PE43670—are offered in a 2-bit, 5-bit, 6-bit or 7-bit configuration. These high-performance DSAs have excellent attenuation accuracy, low insertion loss and high linearity. The four products are available in compact QFN packages. 

For 1K-quantity orders, the PE43620 DSA (2 bit, 50-ohm) is $0.63 each; the PE43650 (5 bit, 50-hm) is $1.44 each. The PE43665 (6-bit, 75-ohm) is $1.23 each, and the PE43670 (7-bit, 50-ohm) is $2.02 each. Volume-production parts, samples and evaluation kits will be available in September.
