A TE11 Ka-Band Gyro-TWT Amplifier with High-Average Power Compatible Distributed Loss

Abstract

Current amplifier research at the Naval Research Laboratory Vacuum Electronics Branch emphasizes techniques to extend the bandwidth and average power capability of gyro devices for millimeter wave radar applications. This paper will discuss the implementation of a wideband high-gain gyro-traveling wave tube amplifier design, with a measured peak output power of 78 kW, gain ^60 dB, and a 3-dB bandwidth of 4.2 GHz (12%) at 52 kW in Ka-band. The 3-dB saturated bandwidth at 70 kW is 6 GHz (17%), which is also the instantaneous bandwidth with appropriately tailored input power (e.g., gain equalizer). The amplifier operates in the TE11 mode and for stabilization employs a high-average power compatible diffractive loading technique.
