The United Stated has convicted two men and a woman of illegally exporting high-tech electronics to Russia.

The convicts, who were among 11 people charged in 2012, were tried in New York on Monday for transporting highly sophisticated electronics from Texas to Russian military and spy agencies, including the Federal Security Service.

All the eleven people were previously charged over a scam that allegedly illegally exported electronics worth millions of dollars to Russia under the guise of civilian deals.

Also, five others have pleaded guilty, including the Russian-American businessman who was the owner of the Arc Electronics corporation in Houston, Texas. The other three people are currently in Russia.

The three people convicted include Alexander Posobilov, a US citizen, Shavkat Abdullaev and Anastasia Diatlova who face up to 185, 65 and 25 years in jail respectively.

Posobilov and Diatlova were also convicted of money laundering conspiracy.

They exported devices used in military hardware such as radar and surveillance systems, missile guidance systems and detonation triggers, US prosecutors said.

"These defendants were key players in a sprawling scheme to illegally export sophisticated technology to Russia," said Robert Capers, US attorney for the Eastern District of New York.

"Through lies and deceit, the defendants and their co-conspirators sold over $30 million of microchips, much of which was destined for Russian military and intelligence agencies."

According to US prosecutors, the majority of the goods shipped in the scam from 2008 to 2012 are not produced in Russia.

All three defendants worked for Arc, whose president Alexander Fishenko pleaded guilty to all charges shortly before the trial and now is awaiting sentencing.

His charges include acting as an undeclared agent of the Russian government.
