Associated Assets from EiC Corporation

Acquisition to Expand WJ Communications’ Leading RFIC Product Portfolio
And Add Significant IP and In Process R&D to Enhance High Power Amplifier Line

June 4, 2004, San Jose, CA – WJ Communications, Inc. (Nasdaq: WJCI), a leading designer and supplier of high-performance RF semiconductors and multi-chip modules (MCM), today announced a definitive agreement to acquire the wireless infrastructure business and associated assets of privately-held EiC Corporation (EiC) of Fremont, CA. EiC designs, develops, manufactures and sells proprietary radio frequency integrated circuits (RFICs) primarily for wireless communications products.

EiC presently markets and sells a broad portfolio of power amplifier products for wireless infrastructure such as cellular, PHS and PAS base stations, repeaters, wireless LAN’s, cable television, and optical networks.

Under the terms of the agreement, WJ Communications will pay approximately $12.5 million in cash and stock for the assets being acquired from of EiC. Additionally, if the EiC operations achieve certain revenue and margin targets over a 24 month period, EiC will receive further compensation of up to $14 million in a combination of stock and cash. The acquisition of EiC is subject to customary closing conditions and is expected to close within 30 days.

“This acquisition further enhances WJ’s strategy of offering customers what we believe is the leading infrastructure RFIC product portfolio in the industry,” said Michael Farese, Ph.D., Chief Executive Officer and President of WJ Communications. “EiC’s respected product family is an excellent complement to our market leading products and we believe we can synergistically ramp WJ’s revenues by

introducing this product family to WJ’s wider range of leading customers. Including the effects of synergy revenues, we expect the acquisition to contribute $8 to $10 million in revenues over the next twelve months, while also significantly expanding our addressable market and accelerating the continuing roll out of our high power amplifiers through the acquisition of significant IP and in process R&D. The highly experienced team of experts coming to WJ from EiC will be instrumental in helping us accomplish our goals as we grow our RFIC business in the coming years.”

As part of the acquisition WJ Communications has acquired rights to the following assets from EiC:

• its leading line of RFICs for the wireless infrastructure market

• intellectual property, patents and patents pending

• certain raw materials, work in process and finished goods inventory

• all of the infrastructure business assets including high reliability 5V,12V, and 28V HBT semiconductor processes

“An integral part of the acquisition is our focus on achieving scale and improving our overall profitability,” added Dr. Farese. “We are on track to achieve EBITDA profitability by the end of the year and believe this acquisition will allow us to further improve our long term business model. Through this acquisition, we expect to achieve additional scale and improving operating margins. Moving forward we will evaluate the best combination of internal and outsourced production to ensure the best long-term business model for the Company to meet our stated goal of 55% or greater gross margins and profitability.”
