摘要
本论文是921项目，要求在Ka频段实现大功率输出功率放大器，具有1W的功率输出，同时有500MHz的带宽性能。该功率放大器将应用在Ka频段雷达固态发射机上。
本文通过对Ka频段矩形波导到微带探针过渡结构形式的大量仿真结果进行分析，总结出在Ka频段过渡结构中不同探针长度所带来的短路活塞距探针长度的变化规律，并在实验中加以验证。该规律在Ka频段矩形波导到微带过渡的工程设计中能够起到较好的指导作用。
通过对金丝压焊互联结构不同形式的分析，确定在Ka频段大功率输出放大器中采用三金丝结构，同时通过调整双金丝，三金丝的金丝间距，总结出金丝压焊互联结构特性随间距变化的一般规律。
为了解决在Ka频段二等分功率分配／合成器中隔离电阻带来的一系列技术问题，应用共面波导和耦合共面波导，利用Ansoft电磁仿真软件仿真设计了二等分功率分配，仿真的结果基本能够满足工程需要，为采用新型传输线实现新的毫米波无源器件提供了参考。
实验结果表明，功率放大器的输出功率在34GHz～35.5GHz频段有大于1W的功率输出，已经能够很好的满足了技术指标的要求，能够应用在固态雷达发射机上。
The thesis is a part of 921 project, which require us to realize a high power output amplifier at Ka band. The amplifier,has an output power over Iwatt and bandwidth of 500MHz,will be used on solid state radar transmitter.
The article analysis quantities of waveguide-microstrip transitions which have different probe length and then summarize the fluctuation rule of distance between the short piston and prob along with the variation of microstrip prob. This rule, which has been tested in our experiments, can be useful in the technique design of waveguide-microstrip transitions at Ka band.
Considering the analysis result of different kinds of bondwire inconnections,The three wire inconnections has been applied in our amplifier, which has little influence to our output power.At the same time, A common rule of charactistic of bondwire along with the wire space changment has been summarize .
To resolve a series of technique problem caused by isolation resitance in power divider at Ka band,we use the CPW ^ CCPW transmission line and Ansoft-Serenade 8.7 engineering software to emulate a power divider at Ka band. The emulation result could satify the engineering demand,and provide a useful reference to realize new millimeter element via new type transmission line.
The experiment result show that the output power of the amplifier has over Iwatt output power at 34GHz?5. 5GHz, which has satisfied the requirement of us.It can be applied on solid state radar transmitter.
