——采用MESFET工艺制造，频率覆盖DC~45GHz，衰减量最高可达31dB

全球领先的微波元件供应商UMS推出了一系列模拟衰减器产品，其工作频率覆盖DC~45GHz，可用于L至Q波段。该系列模拟衰减器采用MESFET工艺制造，栅极长度为0.7μm，具有穿过衬底的通孔和空气桥能力。其衰减量高达31dB，且可精密控制衰减量，从而为后级电路提供大小合适的信号，在增益控制系统中可避免后级放大器的饱和。

该系列模拟衰减器最大的插入损耗仅为6.5dB，极大的减小了接入衰减器对信号损耗的影响。同时，该系列衰减器具有极小的驻波比（如CHT3091：2:1），能够尽可能地降低信号的反射，不仅如此，其P-1dBm最大为25dB，使其拥有极好的线性输出范围。

该系列模拟衰减器体积小，如CHT3091采用QFN封装，体积仅为0.91*0.86*0.10mm，有效减小了电路板面积，其可广泛应用于通信系统增益控制电路中。

主要特性：
• 工作频率：DC-45GHz
• 衰减量：最高达31dB
• 插入损耗：最大仅为6.5dB
• P-1dBm：最大25dB

主要应用：
• 增益控制电路
