A MOBILE phone transmitter maker says a move to a new North-East factory has helped increase revenues as its battles against contract delays.

Filtronic, of Netpark, Sedgefield, revealed its broadband division recorded revenues of £9.7 million for the financial year to May 31, compared to £8.1 million in 2013.

But the company, which employs about 85 North-East staff and works on chips linking mobile smartphones to networks, said its wireless division has seen projects deferred as operators delay changes.

Bosses said wireless revenues slipped to £23 million from £31 million for the year to May 31, leading to predicted £500,000 operating losses.

However, it said: “The board still expects some of the wireless operator projects to deliver revenue in the 2015 financial year, but the timing still remains uncertain.

“The increasing complexity and high levels of data traffic being generated by 4G demand is reshaping the cellular telecoms market.

“The company has continued to address projects from operators, but the number of opportunities has been decreasing and programmes where the firm has developed products have been subject to customer delays resulting in a temporary reduction in wireless.”
