产品描述：SK4系列的单刀双掷开关是离散的或者是MMIC的PIN二极管开关。反射性和吸收性开关都可以达到18GHz，但只有反射开关可以提供18GHz以上。为了更好的控制和系统集成，同轴开关内会集成有TTL驱动，波导开关会外置TTL驱动。吸收性开关在“开”和“关”状态下呈现出很好的回波损耗，但开关的嵌入损耗和开关的成本就会相对的高了。另一方面，在“OFF”状态下，通过缩短传输路径达到一定的隔离度，反射性开关的VSWR不会太理想，也会反射信号。但反射性开关的优点在于它的高功率处理能力和低成本。
产品特性:频率覆盖0.5到80GHz、分反射和吸收两类、低插入损耗和高隔离度、标准温度范围-10 to +60 ℃、控制：高TTL
