Deng Hui-mei · Modern Electronics Technique · 2010
By analyzing the working principle,performance characteristics and typical applications of the frequency synthesizer ADF4360-4,a GPS signal source system taking FPGA chip and the frequency synthesizer ADF4360-4 as the core part is proposed,and the overall and module design schemes are presented.Each module is designed and implemented.The results of the test simulation show that base band / IF module with the FPGA chip as the core part can complete BPSK modulation and spread-spectrum modulation of a GPS signal,and realize the output of GPS digital IF signal;and also RF module with frequency synthesizer ADF4360-4 as the core part can achieve the up-conversion function and implementRF modulation of the signal.
