BOSTON, MA – October 11, 2006 – Teradyne, Inc. (NYSE: TER) announced AMI Semiconductor (NASDAQ: AMIS), a leading manufacturer of integrated mixed-signal and structured digital semiconductor products, received delivery of the 150th Gen4 Microwave instrument for use with the microFLEX(TM) test system. AMIS selected the Teradyne(R) Gen4 Microwave test solution after an extensive evaluation process with a focus on technical performance and ability to deliver the lowest cost of test for its portfolio of industrial and medical devices. AMIS has deployed multiple Gen4 options at its engineering sites and production facility in the Philippines.

 AMI Semiconductor’s market-focused wireless capabilities provide customers with system-on-chip (SoC) solutions that significantly reduce system cost, power consumption, form factor, and time-to-market for short range, low data rate wireless applications. AMIS will use the broad range, robustness and accuracy of the Gen4 module to test its leading edge wireless products that provide solutions for customers in the automotive, medical, industrial, and commercial markets.

According to Gartner Dataquest, Teradyne continues as the market leader for RF/wireless test solutions with over 50% market share covering systems that test RF semiconductors for the wireless device market.

Teradyne’s Gen4 Microwave option covers the broadest range of RF semiconductor test applications in the marketplace and enables the lowest cost of test through scalable multisite test. The Gen4 Microwave instrument can be configured from 4 to 38 RF ports and offers a full range of scalar and vector source and measurement capabilities. Users also have the ability to perform functional test via modulated signal generation and analysis functionality for mainstream wireless protocol standards.

“AMIS performed a comprehensive vendor evaluation to select a next generation wireless test system,” said Craig Nelson, Director Worldwide Mixed-Signal Products Test and Development, AMI Semiconductor. “We selected the microFLEX with the Gen4 Microwave instrumentation for its proven functional performance as well as its high throughput and test economics.”

“Teradyne continues to maintain clear market leadership in RF ATE,” said Dave Trounson, General Manager, Semiconductor Test Wireless Business Unit, Teradyne. “We can attribute our significant wireless market share to the broad range of wireless markets our RF test solution serves and the technical and economic requirements it meets. It is not just a niche test solution, but a broad based RF ATE solution. “
