    • A common interface (10) for a PIM sensitive diplexing filter (30) is provided in a non-contacting, or isolated, configuration while providing PIM reliability, ESD conduction and thermal conduction, making it ideal for high power space applications. The common interface (10) is a one-piece construction of a diplexed, or multiplexed, coaxial, or squareax, transmission line that is constructed with a direct non-contacting (34, 36), or connectionless, interface. Terminations (26, 28) connect the inner conductor (20) to the outer conductor (12) of the interface (10) making the device one integral piece yet providing the necessary isolation through non-contacting interface with a PIM sensitive device (30), and terminations (26, 28) that provide thermal and ESD conduction necessary for PIM reliability (Fig. 2).
    • 用于PIM敏感双工滤波器(30)的公共接口(10)以非接触或隔离的配置提供,同时提供PIM可靠性,ESD导电和热传导,使其成为高功率空间应用的理想选择。 公共接口(10)是由直接非接触(34,36)或无连接接口构成的双工或多路同轴或正方形传输线的一体式结构。 端子(26,28)将内部导体(20)连接到接口(10)的外部导体(12),使得该装置成为整体,同时通过与PIM敏感装置(30)的非接触界面提供必要的隔离, ,以及提供PIM可靠性所需的热传导和ESD传导的终端(26,28)(图2)。
