(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 per formance ka-band amplifiers for earth-satellite communications. these products, based on high reliability m ilitary products, are now av ailable for long-life high- performance commercial applications. mpp offers a wide vari ety of ka-band products, at power levels ranging from 250 watts to 1 mw continuous wave. the VKA-7934 klystron product lin e 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. expected operating parameters power output 750 to 1500* watts beam voltage 10.5 kv beam current 1.30 a frequency 27.5 to 31.3 ghz bandwidth up to 250 mhz (-1db) tunable bandwidth 1.25 ghz gain 40 db cooling method forced air coolant flow rate 1150 lbs/hr pressure drop 3 psig total weight ~50 lbs size 10.5h x 8 x 8 inches *750 watts tunable, 1500 watts fixed tuned. outline features high power low operating voltage up to 125 mhz instantaneous bandwidth 1 ghz tunable and fixed-tuned options available air cooled rare-earth permanent magnet focusing c pi[
