Abstract

To increase the bandwidth of conventional over-mode traveling wave tubes (TWTs) with single-mode existing (SME) in an operation band, a theory on over-mode TWTs with multi-modes coexisting (MME) in the operation band is presented in this paper. To verify this theory, G-band dual-beam and shunted coupled Hughes-type coupled-cavity TWTs with MME and SME are investigated. The particle-in-cell simulation analysis confirms that, compared with SME TWT, the MME TWT can not only operate stably but also has 2.24 times bandwidth and a large increase in the output power.
