Abstract
A low-noise traveling wave tube amplifier operating over the double band from 8-18 GHz with a maximum noise figure of 8.5 db has recently been developed. This amplifier has a nominal small signal gain of 30 db, a gain variation of less than 6 db and a saturated power output of +5 to +10 dbm. The low-noise figure and power output performance exceeds that of presently available Ku-Band amplifiers, and is comparable to presently available X-Band amplifiers as well. The amplifier package, consisting of tube, magnet and integral power supply, weighs 18 lb, has a maximum height of 4.75 in. and is 12 in. long.
