摘要： Apparatus for processing microwave signals at two predetermined frequencies. Signals at a first predetermined frequency are received or transmitted at one end (25) (input port) of a microwave transmission line (23) whose other end (26) is utilized as a common output port for transmitting and receiving signals at both predetermined frequencies. A band rejection portion is provided which comprises first and second rejection resonators (30, 37) orthogonally disposed along the transmission line (23) at two predetermined positions. A bandpass portion, comprised of a plurality of collinearly aligned bandpass resonators (47, 48) is disposed at a third predetermined position along the transmission line (23). Signals at a second predetermined frequency are transmitted or received at a second input port (55) which is part of the bandpass portion. All resonators are capacitively coupled together and to the tranmission line. Signals at both predetermined frequencies may be applied to the first and second input ports (25, 55) and are combined in the transmission line (23) by the filtering action of the resonators (30, 37, 47, 48). Conversely, signals having both predetermined frequencies may be applied to the output port (26) and separated in the transmission line such that signals at the first predetermined frequency are provided at the first input port (25) and signals at the second predetermined frequency are provided at the second input port (55). Also, signals at one frequency may be transmitted by way of the diplexer while signals at the second frequency are received thereby, or vice-versa.
摘要翻译： 用于以两个预定频率处理微波信号的设备。 以微波传输线路（23）的一端（25）（输入端口）接收或发送第一预定频率的信号，该微波传输线路的另一端（26）被用作用于在两个预定频率处发送和接收信号的公共输出端口 。 提供一个带阻部分，它包括在传输线（23）的两个预定位置正交放置的第一和第二抑制谐振器（30,37）。 由多个共线排列的带通谐振器（47,48）组成的带通部分沿传输线（23）设置在第三预定位置。 以第二预定频率的信号在作为带通部分的一部分的第二输入端口（55）处被发送或接收。 所有谐振器都电容耦合在一起并传输到传输线。 两个预定频率的信号可以施加到第一和第二输入端口（25,55），并通过谐振器（30,37,47,48）的滤波作用在传输线（23）中组合。 相反，具有两个预定频率的信号可以施加到输出端口（26）并在传输线中分离，使得在第一输入端口（25）提供第一预定频率的信号并且提供第二预定频率的信号 在第二输入端口（55）处。 而且，一个频率的信号可以通过双工器传输，而第二个频率的信号由此被接收，反之亦然。
