In the mid-nineties, UCSB electrical and computer engineering professor Bob York and his team of researchers began working on solving a technology problem for the telecomm industry: how to amplify high frequency signals for use in high-power telecomm.

Traditional techniques used wires on a circuit board to split one signal into many signals, amplify each of those, and then combine them to produce a single amplified signal. In 1996, Professor York and his grad student, Angelos Alexanian, developed an entirely new approach. Instead of using wires to split a signal, they broadcasted the signal inside a device and used numerous antennae to receive the signal then amplify it. In doing so, they eliminated the inefficiencies that had plagued the old method and made efficient, high-frequency telecomm possible.

In 2004 Wavestream, a communications company based on technology developed at CalTech, began licensing the technology from UCSB for use in their high power solid state amplifiers. Seeing the value in UCSB’s technology, and being familiar with the process of licensing technology from universities, they began producing amplifiers using both technology developed at UCSB (“deck” amplifiers) and technology developed at CalTech (“grid” amplifiers).

The last nine years have seen Wavestream grow from a small university startup to a thriving company with a global impact, and UCSB has played a major part in that growth. The technology developed at UCSB by Professor York is currently used in 90% of the amplifiers Wavestream manufactures.


About TIA:
The UCSB Office of Technology & Industry Alliances (TIA) was established with two primary responsibilities: to manage the intellectual property developed through UCSB research (including out-licensing) and to manage the many agreements with industry partners that support research collaborations (including research agreements, material transfer agreements, non-disclosure agreements and memorandums of understanding).
