摘要

介绍了一种ku波段太赫兹频率调制连续波(FMCW)频率源的设计方案和实现。经过程序分析，采用锁相环(PLL)芯片HMC703和DDS芯片AD9910，形成了DDS和PLL的混合系统设计。通过系统调试，频率源输出功率在12dbm以上，杂散信号抑制- 45dBc，功率平坦度±1dB。此外，系统的信号频率可以从最小17.1GHz到最大19.1GHz。

A Ku-FMCW Frequency Source for THz

A design scheme and implementation of a Ku-Band Frequency Modulated Continuous Wave (FMCW) frequency source for THz is introduced in the paper. After program analysis, a hybrid system design of DDS and PLL is formed, using the phase-locked loop (PLL) chip HMC703 and the DDS chip AD9910. Through debugging the system, the frequency source output power is above 12 dBm, with spurious signals suppression of −45dBc and power flatness of ±1dB. In addition, the signal frequency of the system can be from minimum 17.1GHz to maximum 19.1GHz.
