You raise an interesting question. What are the design tradeoffs
that drive choosing between a ten cent resistor and a circulator?

The design tradeoff is that the ten cent resistor will
not work.

So why don't you prove my contention that the impedance
encountered by the reflected wave is 450 Ohms incorrect.

Walter Maxwell did it for me.

Here is how. Using my 450 Ohm value for the impedance
compute the reflection coefficient at the generator
using RC = (Z2-Z1)/(Z2_Z1).

Invalid! If it were that easy my ten year old grandson
would already be an RF engineer.

I await the analysis.
