A Lexington businessman has been charged with trying to sell sensitive technology that was stolen from his former employer, Norwood electronics company Analog Devices Inc.

A federal grand jury in Boston indicated Haoyang Yu and his company Tricon MMIC LLC with 12 counts of misappropriating Analog Devices’ trade secrets, and with three counts of smuggling for selling electronic components to a customer in Spain in violation of US export control laws. Yu was scheduled to appear Friday in US District Court in Boston.

Yu, a Chinese-born naturalized US citizen, came to the United States on a student visa in 2002, and became a permanent resident in 2009 and a citizen in 2017, according to prosecutors. In 2014, he joined Analog Devices as a design engineer, working on the company’s microwave integrated circuits, which are used in a variety of radio devices for civilian and military use. Yu is charged with downloading hundreds of company files full of technical information about the circuits, and storing the data in his personal Google Drive account.

Yu and his wife formed Tricon MMIC in March of 2017, the government said, and he resigned from Analog Devices five months later. The US government alleges Yu’s business has sold about 20 electronic components that are identical to those sold by Analog Devices. Yu also worked as an employee of an unnamed defense contractor while running Tricon.

The trade secrets and smuggling violations carry penalties of up to 10 years in prison and a $250,000 fine for each count.

Tricon MMIC did not respond to requests for comment.
