September 20, 2010

Adding long-time design partner, strengthens company's leadership position in high capacity radio technology

Paramus, New Jersey, September 20, 2010Ceragon Networks Ltd. (NASDAQ: CRNT),
the provider of high-capacity, 4G/LTE-Ready wireless backhaul networks, announced today that
it has acquired all the shares of privately-held Elxys Innovations, of Athens, Greece. Elxys is a
designer of advanced, next-generation radio-frequency integrated circuits (RFIC). The acquisition
solidifies Ceragon’s leadership in RF design and allows it to further optimize its core radio
technology. By strengthening the radio design team with a group of seasoned professionals in the
RFIC domain, Ceragon will continue to offer its customers superior radio performance, higher
capacities, reduced power consumption and better overall cost.

“Mobile networks are becoming more and more dependent on high-capacity wireless
backhaul,” said Ira Palti, President and CEO of Ceragon. “We believe that the next generation
microwave radios will be based on highly integrated RFICs. Adding a group of proficient RFIC
engineers will allow us to reach higher levels of integration while continuing to stretch the
envelope in terms of radio capacity, reliability and availability. In the process, it will create a
significant product differentiation for Ceragon.”

“We are very excited to be joining the Ceragon family,” said Emmanouil Metaxakis, Chief
Executive Officer and co-founder of ELXYS Innovations. “We have had a successful business
relationship with Ceragon over the past few years, and we look forward to continue incorporating
our radio technology with Ceragon products to substantially expand their performance and
capabilities.”

Elxys has been Ceragon’s design partner for a number of years. The company specializes
in analog, RF, millimeter-wave and mixed signal integrated circuit design spanning from
baseband up to 77 GHz. Total consideration was $1.6 million plus 200,000 restricted share units
to Elxys founders who are now Ceragon employees.
