Improving Return Loss Using Two 100-Ohm Terminating Resistors When terminating an RF transmission line, why might we use two 100 Ω resistors in parallel instead of a single 50 Ω resistor? Using two resistors can provide a better impedance match over a broader frequency range. This improvement is related to the current distribution within a … Continue reading Improving Return Loss Using Two 100 ohm Terminating Resistors
