    Abstract

    A W-band gyro-TWA has been developed to provide high output power and wide bandwidth. This letter presents the upgrade of the input signal generation of the W-band gyro-TWA, and the experiment results with frequency-swept input signals. The results show a 30 dB gain was achieved at a 1 GHz bandwidth input signal when the gyro-TWA was driven by a 40kV, 1.5 A electron beam.
