Samsung Electronics Co. Ltd and Athena Semiconductors Inc. have developed the industry's three-transceiver RF device for MIMO in a single IC.

The companies explained that the tight integration of the single-device, called TRINI, dramatically undermines the cost of all other solutions, which require multiple devices to implement MIMO applications. The small footprint and cost rivals even that of existing wireless device solutions, making a compelling case for implementation of MIMO-based products now to realize dramatic bandwidth and reach performance benefits promised by MIMO technology. At the heart of TRINI is OptimRF technology that Athena Semiconductors pioneered to build high performance CMOS RF transceivers at low cost. OptimRF transceivers use Athena's patent-pending, modified direct conversion architecture designed for extensive digital calibration at system level. It results in OptimRF transceivers delivering high performance at low cost due to an increase in the yield of functional RF chips.

The newly developed, OptimRF-based three-transceiver ICs aid in fulfilling MIMO's capabilities of providing a data rate that is far higher than existing 802.11a/g standards-based equipment, increasing from 54Mbps to more than 200Mbps, opening up new markets for wireless vendors. All the while, OEM and ODM implementing the TRINI can realize significant go-to-market advantages from this smaller footprint single-device. Use of familiar CMOS technology provides a low power-consumption, low-cost solution for MIMO implementations that also enables seamless integration all with a single device.
