紧凑轻量化设计,提供独特的信号质量和效率

R&S®PKU100 固态功率放大器系列适用于 Ku 频段,峰值功率达 400 W 和 750 W, 兼具一流效率和紧凑设计。强大的可选自适应线性化功能创新地改进射频参数。因此,此系列放大器集成固态放大器和电子管放大器的优点。

特性和优点

紧凑、轻巧

提供室内和室外型号

400 W 室内型号仅重 18.3 kg(含电源),且仅需 3 RU 机架空间。坚固耐用、可防风雨的室外型号符合 IP65 标准,重量仅为 23 kg,并且可以直接安装到天线上。同等固态放大器通常要重一倍。高功率放大器采用固态技术提供 750 W 饱和功率,且外形极为紧凑,在市场上独一无二。

自适应线性化

极其出色的频谱纯度

这款高功率放大器率先提供适用于 Ku 频段的自适应线性化功能。这可以最大限度地减少互调产物,优化功率效率。线性化器可自动适应并提供一流的信号性能,无需任何用户交互或调整。此功能可显著改善传输质量,尤其是对于高阶调制方案而言。

灵活的电源性能

电源冗余

放大器可以选择安装冗余电源, 甚至可以由不同的电源设备供应这些电源。这样,即使电源网络关闭或电源模块出现故障,也能保证高可用性。室内型号支持热插拔电源,室外型号具有易于更换的电源模块。R&S®PKU100 的另一个独特之处在于可以使用 48 V 直流电源,非常有利于移动装置。

功率效率媲美电子管放大器

功率效率超过 20%

放大器采用创新的固态设计,实现可与行波管放大器 (TWTA) 相媲美的一流效率。例如,400 W 型号仅需使用 1300 W 主电源,即可提供 180 W 射频平均功率。
