content: Subseries 11 consists of materials documenting TriQuint Semiconductor, Inc.'s work. TriQuint was a division of Tektroninix, Inc., a manufacturer of analog and mixed signal gallium arsenide (GaAs) integrated circuit products. TriQuint supplied custom radio frequency (RF) and Gallium arsenide (GaAs) chips for Magellan's hand-held GPS systems and tested its chips. Documentation includes trip summaries and observations to TriQuint by Don Rea, a Magellan engineer as well as technical drawings, memorandums, development schedules, invoices, purchase orders, and tests results, production quantity and costs, and specifications.  In 1986, Don Rea met Gary Barta, then principal engineer at TriQuint through his frequent visits to the company. Barta led the engineeering development of the an integrated circuit which combined the GPS L-band low-noise pre-amplifier, UHF local oscillator, down converter and high speed digital divisers on a single gallium-arsenide chip.  Nothing like this had been done before for a cost senstive commerical application. Barta later joined Magellan in November 1988 as Vice President of Engineering and made the chip he had designed actually work in the environment of a hand-held product.
