MtronPTI Introduces WiMAX Cavity Filter Series

This is the Only System of Its Type On the Market


ORLANDO, Fla., May 27, 2008 (PRIME NEWSWIRE) -- MtronPTI, a leading producer of frequency control and filter products, has introduced the only configurable cavity filter system on the market designed specifically for WiMAX applications. MtronPTI is a wholly owned subsidiary of the LGL Group, Inc. (AMEX:LGL)

WiMAX (Worldwide Interoperability for Microwave Access) is a highly advanced telecommunications technology that provides wireless service over long distances. According to Dick Thompson, MtronPTI's VP of Sales and Marketing, WiMAX technology is forecast to contribute as much as $7.7 billion in revenues to the telecommunications industry by 2011*. In early May, Sprint and Clearwire agreed to roll-out a nationwide WiMAX Agreement**.

As a wireless alternative to cable and DSL, "WiMAX will allow the wide area, broadband roaming access of wireless devices, such as lap top computers, to the communication system's back bone. The currently available Wi-Fi, a popular wireless application used in home networks and mobile phones, only provides access in small fields of use. WiMAX will also permit more mobility and flexibility of technology use," Thompson said.

"Unique Position"

Marc Gabelli, Chairman of the LGL Group, said, "We anticipate that growth in demands on communications and network infrastructure will continue unabated for the next few years. Users are rapidly adapting to the industry's offering of improved content, faster speeds and enhanced mobility experience. Since its restructuring and reorganization, our subsidiary -- MtronPTI -- is in a unique position to supply frequency management solutions to support this growth," Gabelli said.

The new MtronPTI cavity filter system, designed for WiMAX applications and other wireless metro area network systems, covers the 2.3-to-2.7-GHz frequency range. These filters allow only the desired signals within the WiMAX frequency band to be passed from antenna to receiver. In today's very crowded RF spectrum they allow the receiver to distinguish between wanted and unwanted signals. This is the only configurable device on the market which allows for short manufacturing cycle time. The design has features that lend itself to applications such as mobile and fixed WiMAX, wireless broadband (WiBro) and Wi-Fi. Standard housings can be rapidly reconfigured permitting reduced lead times for custom applications.

"The WiMAX Cavity Filter Series is a powerful response to the ever evolving technology demands of our most successful customers," commented Joe Doyle, VP Engineering at MtronPTI. "We are heavily engaged with major players in this technology sector as an overall strategic supplier. This level of technological advancement can only strengthen our relationships with these customers."
