本文介绍了一种为支持行星探测太赫兹光谱仪仪器而开发的宽带28-34 GHz频率合成器模块。所介绍的模块具有低功率运行和小形状系数，可与NASA行星任务苛刻的有效载荷要求兼容。该模块的核心是一个CMOS片上系统（SoC），包含一个基于欠采样鉴相器（SSPD）的锁相环，功率放大器，功率传感器和数字校准。演示的模块从USB连接中获得的总功率为81.2 mW，覆盖范围为28-34 GHz，整个频段的输出功率优于-4.0 dBm。所提供的中频带相位噪声测量值为-96.6 dBc/Hz，在偏离载波1 MHz时进行评估。
This paper presents a wide-band 28-34 GHz frequency synthesizer module developed to support THz spectrometer instruments for planetary exploration. The presented module features low power operation and a small form factor to be compatible with the demanding payload requirements of NASA planetary missions. The core of the module is a CMOS System-on-Chip (SoC) containing a sub-sampled phase-detector (SSPD) based phase lock-loop, power amplifier, power sensor and digital calibration. The demonstrated module draws a total of 81.2 mW of power from a USB connection and provides coverage from 28-34 GHz with output powers better than -4.0 dBm across the entire band. The offered mid-band phase noise is measured at -96.6 dBc/Hz evaluated at 1 MHz offset from the carrier.
