Development of E-band 81~86 GHz Traveling Wave Tube Amplifier
An E-band continuous wave Traveling Wave Tube Amplifier(TWTA) for communication is presented. The TWTA integrates the E-band folded waveguide traveling wave tube with the miniaturized high-voltage power supply. It can be powered by low voltage supply in the outer part. The main properties of TWTA include operating frequency 81~86 GHz, saturated output power >80 W, small signal gain >38 dB, total efficiency > 22%, size of 38 cm×20 cm×6.3 cm and airborne environmental adaptability. The TWTA bears the advantages of high power, high efficiency, miniaturization, and high reliability.
