摘要
描述了一项技术发展，该技术在高功率、高性能固态放大器方面取得了明显的进步。在37千兆赫下，5瓦的输出功率通过一个五级放大器实现。三个阶段以负电阻模式工作，带宽为2ghz，最后两个阶段为注入锁定。放大器的总增益为33 dB。两个功率级采用高效率的功率组合。计算机辅助设计在负阻放大器的开发和多二极管功率组合结构的建模和优化中得到了广泛的应用。新型宽带环行器耦合各个级，并提供级间隔离，插入损耗水平为每路0.1 dB。整个放大器，包括二极管电流调节器，被封装在6 x 8 x 3英寸的外壳中，重9磅。
A technology development is described which has clearly advanced the state-of-the-art in high power, high performance solid state amplifiers. Five watts of output power at 37 GHz were achieved with a five-stage amplifier. Three stages operate in the negative resistance mode with 2 GHz of bandwidth, the final two stages are injection locked. The total amplifier gain is 33 dB. High efficiency power combining is used in the two power stages. Extensive use has been made of computer aided design, both in the negative resistance amplifier development and in the modeling and optimization of the multiple diode power combining structures. Novel broadband circulators couple the individual stages and provide interstage isolation with insertion loss levels of 0.1 dB per path. The entire amplifier, including diode current regulators, is enclosed in a housing 6 x 8 x 3 inches in size, and weighs 9 pounds.
