摘要

微波功率放大最特殊的军事需求之一是宽带能力。事实上，为了满足电子战规范，放大器必须提供（从 S 波段到 Ku 波段）高水平的输出功率，同时考虑到功率附加效率（PAE）和成本。在 6-18 GHz 瞬时带宽范围内，介绍了 MMIC（HBT 器件）和 TWTA（MPM）取得的成果。当前和预期的结果表明，系统设计者必须考虑到重大改进：这将在不久的将来导致这两种技术之间的广泛竞争。

SSPAs & TWTAs: an evolutive situation for electronic warfare applications

One of the most specific military needs in microwave power amplification is wide band capability. Indeed, in order to fulfil electronic warfare specifications, amplifiers have to provide (from S- to Ku-band) a high level of output power taking into account Power Added Efficiency (PAE) and cost. Results obtained on MMICs (HBT devices) and TWTAs (MPMs) are presented in the 6-18 GHz instantaneous bandwidth. Current and anticipated results show that systems designer will have to take major improvements into account: this will lead to extensive competition in the near future between these two technologies.
