Abstract

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.

SSPA 和 TWTA：电子战应用的发展形势

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。
