IDT's micro networks unit, with operations in Worcester, Mass. and Auburn, N.Y., designs and manufactures data conversion products, custom modules, and a broad line of filters, oscillators, and delay lines based on surface acoustic wave (SAW) technology.

Spectrum Control (Fairview, Penn.) sells custom electronic solutions for the defense, aerospace, communications, and medical industries worldwide.

The transaction, which has already received approval by the IDT (San Jose) board, is expected to close by the end of November. "Our Micro Networks business has been a stable business for IDT for many years. However, we continue to sharpen our focus on analog-intensive, mixed-signal solutions for the communications, computing and consumer markets,'' said Ted Tewksbury, IDT president and CEO, in a statement.

Indeed, IDT has made several moves to sharpen its focus. In October of last year, IDT purchased the video processing technology and related assets from Silicon Optix Inc. for an undisclosed price.

In April, IDT sold the sell assets of its network search engine products to NetLogic Microsystems Inc. for $90 million.

Moving into a hot market, IDT in June purchased the touch sensor technology assets from now-defunct Leadis Technology Inc.

Shareholders of Tundra Semiconductor Corp. in June approved the firm's acquisition by a wholly owned subsidiary of IDT.

In August, IDT moved towards a fabless model. As part of the plan, IDT will shut down its fab in Oregon and will transfer the production to Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC).
