                    Filtronic plc and RF Micro Devices Inc.: 
      Strategic Supplier Relationship for High Volume Supply of pHEMT GaAs 
                    Integrated Circuits from Newton Aycliffe
    

Filtronic plc ('Filtronic'), a leading global designer and manufacturer of
customised microwave electronic subsystems and components for the wireless
telecommunications and defence industries, and RF Micro Devices, Inc., ('RFMD')
a world-leading manufacturer of proprietary radio frequency integrated circuits
(RFICs) for wireless communications products, based on RFMD's leading HBT GaAs
technology, announce the signing of a supply agreement for the manufacture of
high volume pHEMT GaAs products on the Filtronic 6 inch processing facility
based in Newton Aycliffe.

RFMD will incorporate Filtronic's pHEMT GaAs products into its own modules aimed
at mobile handset and WLAN applications.

Under the terms of the agreement Filtronic has become RFMD's Tier 1 supplier for
GaAs pHEMT technology, where RFMD will use Filtronic as its preferred supplier
of pHEMT integrated products for all its requirements. Multi throw GaAs pHEMT
switches are required in handsets to enable band/mode switching and these are
optimally manufactured using pHEMT GaAs technology.

Filtronic and RFMD have been collaborating to develop and qualify a range of
multi-throw switch products. Volume production is due to commence Q2 2005 with
initial pre-production already underway.

Commenting, Professor David Rhodes, Chairman, said: 'The addition of RFMD as
customer for the foundry at Newton Aycliffe is a major step in delivering our
strategy of merchant and custom semiconductor product sales. Filtronic looks
forward to supporting RFMD in their many projects going forward.'
