Peraso Launches WiGig Radio Chip

24 December 2014

Peraso Technologies Inc. (Toronto, Ontario) has announced the immediate availability of its 60GHz WiGig RF IC for consumer electronics.

The chip, which operates with a carrier frequency between 57 and 63GHz is available in two BGA package options, with part numbers PRS1125 and PRS1025, the second of which includes an integrated antenna. The Peraso RF IC coupled with the recently announced Peraso PRS4000 WiGig baseband IC, is suitable for implementing a USB 3.0 dongle, a device. The PRS1025/1125 targets a variety of consumer electronics devices, including mobile phones, laptops, tablets, monitors, TVs, WiFi access points.

WiGig offers data rate of up to 4.6-Gbits per second and thereby opens up applications beyond the scope of conventional WiFi connectivity such as screen mirroring of 4k video as well as moving wireless networking up to gigabit rates.

An additional feature of the PRS1025/1125 is support for the WiGig OOK mode, which allows short-range low-cost applications such as wireless connectors. The PRS1025/1125 silicon area is less than 5 square millimeters and the packaged devices are 49 square millimeters and 36 square millimeters, respectively. Devices are designed to operate over industrial temperature range.

Five years' work

"This product is the culmination of five years of development effort at Peraso," said Ron Glibbery, CEO of Peraso. "We are one of the few companies in the world actually shipping a production version of a WiGig radio. This is a major milestone for the company."

Peraso has been an active participant in the standardization of 60GHz technology for several years, including membership in the Wireless Gigabit Alliance (WiGig) since 2010, as well as participation in IEEE 802.11ad. More recently, Peraso has been an active member of the WiFi 60GHz task group, and has been an active participant in the WiFi 60GHz interoperability program since October, 2013.

The PRS4000 has been available through an early access program since September. The device includes an 802.11ad compliant MAC/PHY, a USB 3.0 system interface, and analog I/Q for seamless use with Peraso’s 60 GHz RF ICs. flexible software architecture, which allows customers to add proprietary functionality to the baseline operation of the device.

Peraso has also closed a $20 million funding round led by new investor Roadmap Capital, with additional financing from existing investors Celtic House Venture Partners, Ontario Emerging Technologies Fund (OETF) and VentureLink Funds. The money is earmarked to bring Peraso's WiGig technology into production and to increase the company's sales and marketing activities.

"With this equity funding we are accelerating the full commercial deployment of our existing silicon and the development of our next generation of phased array products," said Glibbery in a statement.
