摘要:

设计了九通道的射频合成信号,构成了多频段的射频信号源。利用频率合成器和中频调制芯片,能够将基带或中频的信号直接调制到射频。最后将九路射频信号耦合成一路,构成多频段的射频信号源。

关键词: 频率合成, 中频调制, 信号耦合

Abstract:

A 9-channel radio-frequency synthesis of signals is designed,which constitutes a multi-band RF signal source.With the help of the frequency synthesizer and IF modulation chip,the baseband or IF signals could be modulated into RF directly.Finally,the RF signal coupled into nine roads all the way to form multi-band RF signal source.

Key words: frequency synthesis;IF modulation;signal coupling
