    • A switch is particularly advantageous for calibration of signal phase between transmitters, and other uses. The switch has a first data input adapted to input a transmit signal from a first transmitter, a first data output, at least one and preferably multiple bidirectional data ports, and a control input adapted to selectively couple in a first case the first data input to one of the bidirectional data ports, and in a second case one of the bidirectional data ports and the first data input to the first data output. By coupling one data port of the switch to a data port of another identical switch, a transmit signal from another transmitter can be ported to the first said switch, and both signals output to a feedback circuit that finds the phase difference and applies it to a new signal input to one of the transmitters. Beamforming and MIMO uses are also detailed.
    • 开关对于校准发射机之间的信号相位和其他用途特别有利。 开关具有适于输入来自第一发送器,第一数据输出,至少一个,优选地多个双向数据端口的发送信号的第一数据输入,以及适于在第一种情况下选择性地将第一数据输入耦合到 双向数据端口之一,在第二种情况下,双向数据端口之一和输入到第一数据输出的第一数据。 通过将交换机的一个数据端口耦合到另一相同开关的数据端口,来自另一个发射机的发送信号可以被移植到第一个所述开关,并且两个信号都输出到找到相位差的反馈电路并将其应用到 新的信号输入到一个发射机。 波束形成和MIMO使用也是详细的。
