双路双波段频率综合器的设计

Design of an X-and Ka-band Double Channel Frequency Synthesizer

介绍了一种双路双波段频率综合器的工程实现,其主要功能是产生X和Ka两个波段的全相参射频发射信号(RF_1、RF_2),射频耦合信号(RFC_1、RFC_2),射频本振信号(RLO_1、RLO_2),高稳定时钟信号(C_1)和参考时钟信号(OSC_1)。频率综合器使用FPGA和AD9910来产生数字基带信号波形,包括无调制信号,二相编码信号(BPSK),线性调频信号(LFM)。

This paper introduces an engineering realization of double band and double channels frequency synthesis. Its main function is to generate X-band and Ka-band RF transmitting signals,RF coupling signals,RF local signals,high steady clock signal,referenced clock signal. The frequency synthesis uses FPGA and AD9910 to generate digital-based signal,containing non-modulation signal,binary phase coding signal(BPSK),linear frequency modulation signal(LFM).
