Rogers Corp. to Showcase New RO4230® High Frequency Circuit Material at Antenna Systems Show '06

Show: Antenna Systems Show
Dates: September 6-7, 2006
Venue: Sheraton Premier Tysons Corner
Vienna, Virginia
Booth #: #19

July 30, 2006 Rogers, CT. Rogers Corporation (NYSE: ROG) will be
introducing its RO4230 high frequency circuit material at this years
Antenna Systems Show.

RO4230 circuit material extends the capabilities of the successful RO4000® product series into antenna applications. This ceramic filled, glass reinforced hydrocarbon based material provides the controlled dielectric constant, low loss performance and excellent passive intermodulation (PIM) response required for mobile infrastructure microstrip antenna uses.

Further, the material is halogen free and meets the worldwide green
standards. As with all RO4000® high frequency laminates, RO4230 laminate processes similar to FR4 and does not require special treatment needed on PTFE-based laminates for plated through hole preparation. Its features include:

o Excellent PIM response
o Higher thermal conductivity for high power applications
o Non-PTFE
o Excellent high frequency performance due to low dielectric tolerance and loss
o Low thermal coefficient of dielectric constant
o Low in-plane expansion coefficient

Typical applications may include cellular infrastructure base station
antennas, satellite radio antennas, and WiMAX base station antennas.

At the show, Rogers will also have on display its broad range of high frequency circuit materials. They are:

o RO4000® Series High Frequency Circuit Material is a glass-reinforced
hydrocarbon/ceramic thermoset laminate system designed for performance sensitive, high volume commercial applications. These laminates and prepregs are designed to offer superior high frequency performance and low cost circuit fabrication. The result is a low loss material, which can be fabricated using standard epoxy/glass (FR4) processes.

o RO3000® Series High Frequency Circuit Material allows design
engineers to meet performance criteria at low cost. These materials combine microwave frequency electrical properties and improved temperature stable performance. The RO3000 material can be used at high frequencies because of its low dielectric loss. The low dielectric loss combined with low profile copper foil results in excellent PIM performance.

Rogers specialty materials are offered worldwide through an extensive network of technical sales offices. Based in Rogers, CT, the corporation manufactures and markets specialty polymer and electronic materials for targeted applications, focusing on communication and computer markets.
