由于未来太空通信需要提高数据速率，因此需要 Ka 频段技术来实现更宽的带宽和更高的数据速率。线性频率转换对于实现高数据速率的高阶调制方案至关重要，这反过来又增强了灵活性和软件定义的功能。本文总结了与跟踪和数据中继卫星系统（TDRSS）频段（26 GHz）兼容的 Ka 频段前向和反向链路频率转换器的关键设计特点和数据结果；未来的工作可以将业务扩展到深空网络 Ka 频段。所开发的技术是一套 Ka 频段发射和接收多芯片模块 (MCM) 频率转换器以及相关的低相位噪声本地振荡器 (LO) 合成器板。这套硬件在S波段和Ka波段之间进行转换。该转换器专为 1 GHz 带宽和可在此 1 GHz 范围内重新调谐的中心频率而设计。 MCM 提供多功能设计，可用于激励器和接收器转换器，并为未来扩展提供空间。此外，MCM 和 LO 合成器构成了一个低功耗系统，激励器硬件的功耗为 1.6W，接收器部分的功耗为 1.8W。最后，LO 合成器在 100 Hz 至 40 MHz 范围内具有低于 2.5 度 rms 的低相位噪声，从而实现高数据速率和高阶调制方案。 1 2
As future communications in space require increasing data rates, Ka-band technology is needed to enable wider bandwidths and higher data rates. Linear frequency translation is essential in enabling higher order modulation schemes for high data rates, which in turn enhances flexibility and software defined capability. This paper summarizes the key design features and data results of Ka-band forward and reverse link frequency translators compatible with the Tracking and Data Relay Satellite System (TDRSS) bands (26 GHz); future work could expand operation to the Deep Space Network Ka-band. The technology developed was a set of Ka-band transmit and receive multi-chip module (MCM) frequency translators with associated low phase noise local oscillator (LO) synthesizer boards. This set of hardware converts between S-band and Ka-band. The translators are designed for a 1 GHz bandwidth and for a center frequency that is re-tunable in this 1 GHz range. The MCMs offer a versatile design that can be used for both exciter and receiver translators and provide areas for future expansion. Furthermore, the MCM and LO synthesizer form a low power system with 1.6W of power consumption for the exciter hardware and 1.8W for the receiver portion. Finally, the LO synthesizer has low phase noise under 2.5 degrees rms from 100 Hz to 40 MHz which enables high data rates and high order modulation schemes. 1 2
