Abstract

The satellite communications market has previously been served by klystrons with grounded collector. Now, CPI has developed a new generation of air-cooled, permanent-magnet (PM) focused, high-efficiency klystrons utilizing a multistage depressed collector (MSDC). We describe the development and production of the VKU-8891M series, pioneering MSDC technology in the direct broadcasting satellite (DBS) market. With a saturated efficiency of 40 percent this klystron far surpasses the performance of a conventional klystron. As a result, this technology saves more than 50 percent of the power required by existing products in this market in average field-operating conditions.
