Glendale, AZ, July 8, 2005 – Corning Gilbert, a subsidiary of Corning Incorporated (NYSE:GLW) has announced the introduction of its smallest push-on, high-performance, microwave interconnect system. The G3PO^TM connector, approximately 30% smaller in size than the GPPO®, has been developed in response to industry demand for increased package density, lower weight, and excellent performance at higher frequencies. Well-suited for a variety of military and commercial applications, the G3PO^TM can be used in radar systems, telecommunications and wireless base station equipment, satellite systems, antenna arrays, etc.

"Corning Gilbert's broad development experience in coaxial push-on interconnects continues to set the industry gold standard for performance. Our innovative G3PO^TM product line will perform at higher frequencies than the current GPO® and GPPO® and will enable our customers to design and manufacture in smaller size packages," said Kathryn Murphy, president and chief executive officer of Corning Gilbert.

The G3PO^TM connectors support increased package density with center-to-center spacing of 0.085" minimum and PCB to PCB stack height of 0.120" minimum. The new connectors are designed for 50 ohms. They feature a frequency range from DC to 65 GHz and an operating temperature range from -65°C to +165°C. Typical VSWR is 1.1:1 to 26.5 GHz and 1.25:1 to 65 GHz. They allow for both radial and axial misalignment with negligible VSWR change and are capable of meeting environmental requirements per MIL-PRF-39012 such as corrosion, vibration, mechanical shock, thermal shock and moisture resistance. Our unique axial and radial misalignment features enable efficient assembly and robust performance under challenging conditions.

The G3PO^TM Standard Blind-mate Interconnect, part number R1R1-0001-01, weighs only 0.2 milligrams. The G3PO^TM product line includes custom blind-mate interconnects, edge-launch and surface-mount connectors, cable connectors — male and female, multi-position blocks in various sizes and detents, hermetic and load connectors. To meet customer specific short lead times, Corning Gilbert offers a fast and reliable turn around in the prototype shop. "We specialize in custom designs that meet our customers' requirements and can be manufactured in short lead times," explained Eric Paulus, design engineering manager. In addition, the products are being manufactured efficiently in high volumes at the production facility in Glendale, AZ.

Corning Gilbert's microwave product portfolio includes a breadth of coaxial push-on and threaded connectors. For more information, visit the Corning Gilbert website at www.corning.com/corninggilbert or contact Corning Gilbert at 1-800-528-0199.
