Filtronic knows wireless inside and out. The company designs and manufactures custom-made microwave electronics sub-assembly components mainly for the wireless telecommunications industry. Its lineup of products are integrated with radios that serve as the backhaul links of telecommunications networks, especially mobile base stations. Products for these stations include transceivers and diplex filters. Filtronic's customers are global original equipment manufacturers such as SELEX Galileo. In 2010 Filtronic looked to gain a foothold in the 3G/4G base station market with the purchase of wireless telecom infrastructure company Isotek.
