The order is valued at approximately US$7.9m (£5.5m) and is follows on from previous orders of US$3.9m and US$2.0m received from the customer in January and early March.
Rob Smith, CEO of Filtronic, said: “We are delighted to have been chosen to work on this challenging and prestigious project and signals a brighter future for the firm.
“We have still got a hell of a lot to do to change the orders into real life sales, but morale is definitely on the way up for the company.”
The company expects fulfilment of the new order will straddle the financial year ending 31 May 2016.
