PALO ALTO, Calif., Nov. 12 /PRNewswire-FirstCall/ -- Communications & Power Industries, Inc. (CPI) has received two contracts totaling approximately $4.8 million to support six multi-frequency cloud radar systems. These radar systems will be used by the Atmospheric Radiation Measurement Program (ARM) Climate Research Facility, one of the U.S. Department of Energy's (DOE's) national scientific user facilities, for fundamental research on the effects of clouds and precipitation on the climate. CPI will provide integrated transmitters for the X-band, Ka-band and W-band weather radar systems; these transmitters will incorporate several of CPI's vacuum electron device technologies and power and control systems. CPI, a subsidiary of CPI International, Inc. (NASDAQ:CPII), is a leading provider of microwave, radio frequency, power and control solutions for critical defense, communications, medical, scientific and other applications.

The permanent systems will be located in Oklahoma, Alaska, Australia and Papua New Guinea. The portable systems will be deployed with ARM's mobile facilities at sites around the world. ProSensing subcontracted with CPI for extended interaction klystron (EIK) and traveling wave tube transmitters, which are key components of the radar systems. Engineering and manufacturing personnel from several of CPI's divisions will participate in the project. Shipments of CPI's products are expected to be completed by the end of calendar year 2010. "CPI's products are playing a vital role in broadening and deepening our understanding of our climate and weather conditions," said Joe Caldarelli, chief executive officer of CPI. "Climate change is one of the critical issues of our time, and we intend to continue to support leading research organizations around the world as they study the role of various aspects of our climate and weather conditions." CPI's high-power, millimeter wave EIKs are the key enabling technology for other prestigious cloud research and weather radar systems, including the 94 gigahertz cloud-profiling radars for the European and Japanese space agencies' Earth, Clouds Aerosols and Radiation Explorer (EarthCARE) mission and NASA's CloudSat Earth Observation satellite.
