隔离电阻器

隔离电阻器是一种精密电阻器，策略性地放置在功率分配器电路中，以防止输出通道之间的信号干扰和反馈。它通过提供受控的阻抗匹配并最小化串扰，确保每个输出端口独立工作，同时允许功率分配器在多个负载之间保持适当的信号分配而不会退化。

隔离电阻器通过在功率分配器的输出端口之间创建受控的阻抗路径来工作。当信号被分配时，任何反射能量或阻抗不匹配在一个输出端口处被电阻器吸收，而不是影响其他端口。这保持了信号完整性，防止驻波，并确保每个输出接收到正确的功率电平，而不会受到其他通道的干扰。

The isolation resistor works by creating a controlled impedance path between output ports of a power divider. When signals are divided, any reflected energy or mismatched impedance at one output port is absorbed by the resistor rather than affecting other ports. This maintains signal integrity, prevents standing waves, and ensures each output receives the correct power level without interference from other channels.
