Abstract : A power amplifier of 50 watts power output, tunable from 1300 to 2400 megahertz, was designed and constructed for use with the power tetrode, type Z-5267. The single-ended coaxial amplifier has a power gain of 10 decibels plus or minus 1/2 decibel across the band at an instantaneous bandwidth of one per cent and a plate efficiency of 25 per cent. Double, noncontacting, one-quarter wavelength, 'bucket'-type choke, tuning plungers are used in both the input and output coaxial cavities. The overall size of the amplifier, including the tuning mechanisms, is 6.75 inches wide by 21.75 inches long. Design considerations and operating conditions are discussed. The Appendix contains lists of materials used and the numbers for the individual parts drawings. (Author)
