WJ Communications Announces Completion of Acquisition

June 21, 2004, San Jose, CA – WJ Communications, Inc. (Nasdaq: WJCI), a leading designer and supplier of high-performance RF semiconductors and multi-chip modules (MCM), announced today that it has completed its previously announced acquisition of the infrastructure business and associated assets of privately-held EiC Corporation (EiC) of Fremont, CA.  EiC designs, develops, manufactures and markets proprietary radio frequency integrated circuits (RFICs) primarily for wireless communications products.

“We are delighted to have completed this acquisition and look forward to fully integrating EiC’s strong technology and talented staff into our operations,” said Michael Farese, Ph.D., Chief Executive Officer and President of WJ Communications.  “The addition of EiC’s products and technology provide a great complement to our RFIC capabilities which will enable us to better serve our current customers and expand into new opportunities in the wireless infrastructure market.”

The consideration paid to EiC by WJ Communications at closing, including deposits into escrow, consisted of $10.0 million in cash and 737,000 shares of WJCI’s Common Stock.  Additionally, as previously announced, 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 stock and cash.   If the targets are achieved in full and EiC is entitled to receive the entire escrow deposit, then the total transaction value will be approximately $26.4 million.
