Abstract :
L-3 electron devices division (EDD) is developing a wideband IOT (WBIOT) with a 1 dB bandwidth greater than ten percent. High efficiency, good linearity, and compact size are provided by emission gated modulation of the electron beam directly at the cathode surface. Through use of a high impedance input circuit and an extended interaction output circuit, the instantaneous bandwidth of existing IOTs is increased by a factor of five, making the WBIOT suitable for use in a broad range of radar and communications applications.
