Gain ICs offers solutions for the next generation of Wi-Fi, cellular communication, RFID item level tagging, and GPS signalling. The firm's Ultraphase Coordination (UPC) technology is a new PLL (phased locked loop) technology which aims to overcome the limitations of existing PLL technology, specifically jitter peaking, to achieve 1,000 times faster phase coordination or tracking bandwidth. The technology has applications in RFID tags, GPS systems, and any data that synchronizes to a clock. One specific application is RFID shopping-cart checkout, or item-level tagging, which can be verified by longer transmission distances and significantly reduced size, cost, and power consumption versus existing methods. The firm's primary products are IP blocks and custom IC chip designs.
