CPI VKA-7934

cpi[
CPI Microwave Power Products’ (MPP) klystrons were the first to be used in both commercial and military satellite
communications uplinks and are now the worldwide standards for this class of operation covering C-band, X-band and
Ku-band frequencies. In 1977, MPP introduced high performance Ka-band amplifiers for earth-satellite
communications. These products, based on high reliability military products, are now available for long-life highperformance commercial applications. MPP offers a wide variety of Ka-band products, at power levels ranging from
250 watts to 1 MW continuous wave.
The VKA-7934 Klystron product line is currently under development. Initial test of the fixed tuned klystron is
complete. Measured data for this klystron can be found on the second page. The tunable klystron will be tested by the
end of this year.
