                INITIAL PRODUCTION ORDERS RECEIVED FOR NEWTON AYCLIFFE


Filtronic plc, a leading global designer and manufacturer of customised
microwave electronic subsystems, announces that its Compound Semiconductor
business at Newton Aycliffe, County Durham, UK, has received initial production
orders from M/A-COM, Inc., to supply RF switches for cellular handsets for a
major non-European OEM. This is scheduled for manufacture over the next three
months with further follow-on orders expected.


The number of volume opportunities identified in Filtronic's Final Results
announcement of 29 July 2002 has since doubled from four to eight, and levels of
production to meet demand from M/A-COM for very high volume OEM requirements are
expected to grow substantially over the next 12 months.


Of the eight specific opportunities M/A-COM have identified, four are with
non-telecommunication major OEMs, for the volume manufacture of switch product
for Wireless Local Area Networks ('WLAN', 802.11a, b and g), which are
anticipated to start early in the first quarter of calendar year 2003.


Commenting, Professor J David Rhodes CBE FRS FREng, Executive Chairman, said: '
The M/A-COM Strategic Alliance signed in November 2001 put together Filtronic's
production facility for Gallium Arsenide semiconductor devices at Newton
Aycliffe with M/A-COM's world renowned position in microwave semiconductor
devices. Filtronic has developed a first class process for the production of RF
switches at Newton Aycliffe with exceptionally high yields and excellent device
performance. The quality, efficiency and cost effectiveness of this process is
outstanding.'
