Peregrine Semiconductor's RF Switches Reach Market Acceptance in the Cable Industry

Peregrine's RF Switches Offer an Easy Transition from DOCSIS® 3.0 to 3.1 Technology with a Dual-Band Architecture

SAN DIEGO – Peregrine Semiconductor Corp., founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, announces its high linearity RF switches are designed into multiple DOCSIS 3.1 certified cable modems. CableLabs, the research and development consortium that develops the DOCSIS specification, has certified the first DOCSIS 3.1 cable modems. Of the certified modems, Peregrine Semiconductor's RF switches--the UltraCMOS® PE42722 and PE42723--are designed into the cable modems that feature a band-select feature. The PE42722 and PE42723 are the only RF switches that enable dual upstream/downstream bands to reside in the same consumer premise equipment (CPE) device.

Before Peregrine began offering the PE42722 and PE42723, CPE devices--such as set-top boxes, cable modems and home gateways--could only support one upstream and downstream band. Extremely high linearity is required to enable and support a dual-band architecture. Peregrine offers the only RF switches with the needed high linearity to meet the standard. By enabling a dual-band architecture, CPEs can comply with the DOCSIS 3.1 cable industry standard, and multi-service operators (MSOs) have the flexibility to offer their customers new and expanded services. MSOs also benefit from the switches supporting both DOCSIS 3.0 and 3.1 technologies, allowing for a simple and cost-effective transition to DOCSIS 3.1 service.

"As the world-wide cable industry transitions from DOCSIS 3.0 to 3.1 technologies, MSOs need to future proof their CPE devices with higher flexibility in addition to backward compatibility," says Duncan Pilgrim, vice president and general manager of Peregrine Semiconductor's high performance analog (HPA) business unit. "Peregrine's high linearity RF switches rise to the challenge and deliver a key selling feature for cable modem vendors. By offering a dual-band architecture, our switches enable a simple transition from DOCSIS 3.0 to 3.1 service."
