                           Filtronic plc: US Disposal

 Agreement to sell certain assets of Filtronic Solid State Business to Teledyne
                            Wireless, Inc. for US$12m


Filtronic plc  ("Filtronic"),  a leading designer and manufacturer of customised
microwave electronic subsystems for the wireless  telecommunications and defence
industries,  announces  that it has entered  into an  agreement  to sell certain
assets of its Filtronic  Solid State ("Solid State")  business,  in Santa Clara,
California,  to Teledyne Wireless,  Inc., a wholly-owned  subsidiary of Teledyne
Technologies Incorporated ("Teledyne" - NYSE: TDY) for approximately US$12m. The
transaction is expected to close on or about December 31, 2003 and is subject to
customary closing conditions.

The proceeds of the disposal,  which is of the electronic  warfare part of Solid
State's  business,  will be used by  Filtronic  to  accelerate  repayment of its
senior notes, of which US$74m is currently outstanding. Filtronic has now bought
and  cancelled  a total of US$96m of its 10% Senior  Notes due 1  December  2005
since 4 February 2002.  Profit before  taxation  attributable to the Solid State
electronic  warfare business for the year ended May 31 2003, was $1.4 million on
sales of $12.5m.  The value of the net assets to be disposed of is approximately
$3.0 million.

Commenting,  Professor  J David  Rhodes CBE FRS  FREng,  Executive  Chairman  of
Filtronic  plc, said:  "We are pleased that the Solid State  electronic  warfare
business will have such a strong new owner in Teledyne. The complementary skills
and business  opportunities  arising through  Teledyne should provide  excellent
growth for the Solid State  business  and  employees.  In the future,  Filtronic
looks  forward to building  upon the strong  relationships  formed with Teledyne
through this transaction."

Solid State designs and  manufactures  customised  microwave  subassemblies  for
electronic  warfare,  radar  and  other  military  applications.  Following  the
acquisition  by Teledyne  Wireless,  the business  will be relocated  from Santa
Clara, California and consolidated with existing Teledyne operations in Mountain
View, California.

Following  the  transaction,  Filtronic  will  retain its Solid  State  compound
semiconductor business in California and employ 19 people there.

Teledyne  is  a  leading  provider  of  sophisticated   electronic   components,
instruments and communication products, systems engineering solutions, aerospace
engines and  components  and on-site gas and power  generation  systems.  It has
operations in the United States, the United Kingdom and Mexico.

Said  Robert  Mehrabian,  Chairman,  President  and Chief  Executive  Officer of
Teledyne  Technologies:  "Solid  State is highly  complementary  to our Teledyne
Wireless  and Teledyne  Microwave  Electronic  Component  units.  Solid  State's
precision YIG-based oscillators, filters and amplifiers serve the same customers
as our traveling wave tubes, voltage controlled  oscillators and other products,
and are used on many of the same military programs."

He added: "We expect to obtain  significant  synergies through the consolidation
of Solid State with our current  military  microwave  subassembly  operations in
Mountain View, California.  Solid State's strong and experienced management team
will  assist  us in our  strategy  to  develop a  broader  line of  specialised,
high-performance  microwave  products for military  radar,  electronic  warfare,
missile and communication applications."
