ParentLattice Semiconductor

SiBEAM was founded to commercialize pioneering millimeter wave wireless technology developed at the labs of University of California, Berkeley. The company was also first to market with wireless gigabit mobile video products. SiBEAM is based in Sunnyvale.


SiBEAM was founded in 2004 by researchers in wireless communications from the University of California, Berkeley. Backed by companies including Panasonic, Samsung, Cisco Systems, and Best Buy.[1][2][3][4] The company raised over $112 million of venture capital financing from U.S. Venture Partners, New Enterprise Associates, Foundation Capital, and Lux Capital in 2004, 2005, 2006, 2008, and 2010.[5][6][7][8][9][10][11] SiBEAM was noted by several publications as one of the promising startup companies in its industry.[12][13]

In April, 2011 SiBEAM was acquired by Silicon Image for $25.5 million in cash and Silicon Image stock.[14][15]

On January 5, 2015 Silicon Image Re-Launched SiBEAM, Inc. as a wholly owned subsidiary to drive market development of millimeter-wave products, technologies and solutions[buzzword] [16]

On March 15, 2015, Silicon Image was acquired by Lattice Semiconductor in an all-cash acquisition, valued at approximately $606.6 million (or approximately $466.6 million on an enterprise value basis).[17] SiBEAM became a direct wholly owned subsidiary of Lattice Semiconductor on June 1, 2015.

On July 18, 2018 Lattice Semiconductor announced that they "will discontinue its millimeter wave business, which is expected to result in approximately $25 million of primarily non-cash restructuring and impairment charges in the second quarter of 2018, and an annualized reduction in operating expenses of approximately $13 million."[18]
