摘要： A telemetry system with a matrixed telemetry switch unit array and a method for determining the switch position of a telemetry switch unit. The switch units include steering diodes and parallel signal paths each with unique resistance values. The signal paths correspond to switch positions and are closed when the switch unit is in the corresponding switch position. A signal source is electrically connected to an input current path and output current path of the array with a corresponding telemetry switch unit coupled into the signal path. A plurality of sensing signals are applied through the array and the resultant signals are measured. The switch position is determined from the resultant signals indicating the resistance value of the switch signal path currently coupled into the array signal path while accounting for the voltage drop of the steering diodes

摘要： A microwave switch for transmitting signals having a plurality of ports and a plurality of signal paths for selective transmission of the signals. Each signal path is disposed between a respective pair of the ports and each signal path has a conducting state in which signal transmission occurs between the respective pair of ports and a non-conducting state in which signal transmission does not occur between the respective pair of ports. The switch also has a plurality of actuators, each actuator being adapted to actuate at least one of the signal paths between the conducting and non-conducting states. At least one of the ports and at least one of the signal paths are located on a first plane and the remainder of the ports and the signal paths are located on a second plane such that there are no cross over points between the signal paths in any of the planes. A switch matrix can be built using this bi-planar switch such that the switches in the matrix are connected without any cross over points.

摘要： An analog processor for use with digital satellites is disclosed. The analog processor is connected between the receiving circuitry of the satellite and a pool of digital on-board processors, and segments the bandwidth of uplink RF beams into sub-bands that can be processed more readily with standard, low-risk, low-power digital processors. Using the present invention, the risk of employing a particular digital processor technology can be managed and optimized. The present invention also provides for the dynamic allocation and reallocation of the available on-board digital processing bandwidth based on the anticipated traffic pattern and changes in the traffic pattern. In addition, the present invention facilitates the use of standard and non-standard redundancy schemes at minimal hardware expense.

摘要： The present invention provides a fully monolithic cross-point switch niatrix and method of operation thereof which overcomes the isolation problems between unconnected ports of the prior art. This is accomplished by the addition of an Isolation Enhancement Network (IEN) connected between each of the input and output transmission lines at each of the cross-points. The switch matrix is comprised of a tiled interconnection of MxN of the 1x1 switch/IEN (SIEN) cells, where N and M are the number of input and output ports respectively. Each of the SIEN cells can be independently configured into one of two operating modes, connected or unconnected. The switching element is configured to provide a high isolation path between the input and output lines in the unconnected mode of operation. In this case, a small fraction of the input signal injected at the input port appears at the output port. This output signal is comprised of two components. The first component arises from a number of stray coupling mechanisms between the input and output lines but does not include the portion of the input signal which passes tllrough the IEN. The dominant area of this stray coupling occurs at the point where the input and output transmission lines cross. The second component of the output signal is purposely injected via the IEN. The IEN couples a small portion of the input signal, adjust its amplitude and phase, and then recouples it to the output line so that the resultant signal has the same amplitude but is 180 degrees out-of-phase with the first component. The result is a cancellation of the two components yielding an improvement in the isolation between the two ports. The compensation signal injected by the IEN into the output line is significantly lower than the main signal component when the switching element is in the connected state, thereby allowing the input signal to be routed to the output with insignificant perturbation.
摘要翻译：本发明提供一种完全单片交叉点开关及其操作方法，其克服了现有技术的未连接端口之间的隔离问题。这通过在每个交叉点处添加连接在每个输入和输出传输线之间的隔离增强网络（IEN）来实现。开关矩阵由1x1开关/ IEN（SIEN）单元的MxN的平铺互连组成，其中N和M分别是输入和输出端口的数量。每个SIEN单元可以独立配置为两种连接或未连接的工作模式之一。开关元件被配置为在未连接的操作模式中在输入和输出线之间提供高隔离路径。在这种情况下，在输入端口处注入的输入信号的一小部分出现在输出端口。该输出信号由两个部件组成。第一个分量源于输入和输出线之间的许多杂散耦合机制，但不包括通过IEN的输入信号部分。这种杂散耦合的主要区域发生在输入和输出传输线交叉的点。输出信号的第二个组件是通过IEN有意地注入的。 IEN耦合输入信号的一小部分，调整其幅度和相位，然后将其重新耦合到输出线，使得所得到的信号具有相同的幅度，但与第一分量相差180度。结果是取消了两个组件，从而改善了两个端口之间的隔离。当开关元件处于连接状态时，IEN注入输出线的补偿信号显着低于主信号分量，从而允许输入信号以微不足道的扰动路由到输出端。
