功率合成器的设计固态发射机有三个主要微波元件:固态功率放大器、把射频驱动功率送给放大器的输入功率分配器以及输出功率合成器。本文讨论设计功率合成器时所涉及的一些问题。通常,同样的条件也适用于输入功率分配器,不过插入损耗和功率容量就不那么重要了。功率合成器收集所有各个功率放大器的输出功率,而把它送至单个功率输出端。这种合成是象一个相干功率相加器那样实现的,而该输出是所有输出放大器组件功率的算术和减去内部损耗。正是其使许多放大器的功率高效率地相加或合成的 Power Synthesizer Design The solid-state transmitter has three major microwave components: a solid-state power amplifier, an RF power driver that delivers RF-driven power to the amplifier, and an output power combiner. This article discusses some of the issues involved in designing a power combiner. In general, the same conditions apply to the input power divider as well, but insertion loss and power capacity are less important. The power combiner collects the output power of all the individual power amplifiers and sends it to a single power output. This synthesis is accomplished as a coherent power summer, which is the arithmetic of all output amplifier components’ power and minus the internal loss. It is the power of many amplifiers that efficiently add or combine
