Design and Implementation of X-Band Linear Sweeping Source Based on HMC703 PLL Frequency Synthesizer
Qin Jucha · 2013
A design and implementation of X-band linear sweeping source based on HMC703 PLL frequency synthesizer is presented. By analyzing the internal structure of HITTITE's HMC703 PLL frequency synthesizer,combining the VOC HMC513 with outputs of 2 division frequency and the HMC703 PLL frequency synthesizer with the discussed working characteristic,a design of 10. 45 GHz ~10. 85 GHz linear sweep source controlled by ARM processor is realized. The simulation software Hittite PLL Design Software is used to simulate and design active loop filter. Through debugging the hardware and programming the ARM processor,a linear sweeping source with a good performance is realized.
