隔离电阻

An isolation resistor is a precision resistor strategically placed in power divider circuits to prevent signal interference and feedback between output channels. It ensures that each output port operates independently by providing controlled impedance matching and minimizing cross-talk, while allowing the power divider to maintain proper signal distribution across multiple loads without degradation.

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.
