摘　　要：为了实现模块化和通用性,本文设计了一种超宽带上变频器,能够覆盖整个超短波频率,为了保证输出频率范围内的平坦度,增加了均衡器作为补偿。文中给出了上变频器的原理框图,详细计算了整个链路的主要技术指标,给出了超宽带幅度均衡器的仿真曲线。测试结果表明,该上变频器实现了超宽带和低杂散,具有较强的通用性。An ultra-wideband up converter which covers the whole VHF band is designed to get modularity and generality. Equalizer is employed here to ensure flatness in output range. Functional block diagram of the up converter is given, while main specifications are calculated via the whole link. S-Parameter curves of ultra-wideband equalizer are also given employ EM simulations. Tests are made after fabrication; the results validated the ultra-wideband and low spur character of the up converter, while good generality is also presented..
