射频同轴开关RF Coaxial Switch(也称射频继电器、射频开关、微波开关、同轴机械开关),是一种通过传输路径路由高频信号的设备。射频同轴开关广泛用于微波测试系统中,用于被测仪器和设备之间进行信号路由。将开关整合到开关矩阵系统中,使您能够将信号从多台仪器路由到单个或多个DUT。通过射频开关的多端口连接,从而允许使用相同系统设置执行多路测试,而无需频繁断开连接。
莱尔微波拥有一支资深的专业射频继电器研发团队,自主研发生产射频同轴开关,频率覆盖DC-67GHz,专注于SPDT(单刀双掷),SPnT(单刀多掷,如SP3T, SP4T, SP6T, SP8T, SP10T, SP12T, SP16T等),DPDT(双刀双掷),DP3T(双刀三掷)等通道结构,射频接口类型包括SMA、N、2.92mm、2.4mm、1.85mm、TNC、BNC、L29、SC等,可选功能包括指示电路、逻辑电路、射频负载、抑制电路等。
目前,莱尔微波已开发出多系列极高频(DC-67GHz)开关产品,在体积、大功率、可靠性、一致性及使用寿命等方面具有国内领先水平,广泛应用于5G通信测试、自动化测试设备、通信及导航系统, 军用航天通讯系统、电子对抗、自动控制系统、精密测量装备、雷达发射机射频信号控制等多种领域。公司已获得ISO9001/14001国际质量管理体系认证,以及GJB9001C-2017国军标质量管理体系认证。
