The number of problems that you will be able to solve will go
up significantly.

Since your use of it yielded erroneous results, I think
I will pass. However, it appears to be much like the
S-Parameter analysis which does yield correct results.

An S-Parameter analysis indicates that you have made an
error in the reflection coefficient, s11, looking into
the 450 ohm transmission line. From HP's Ap-Note 95-1,
s11 is defined as the "Input reflection coefficient
with the output port TERMINATED BY A MATCHED LOAD."

You calculated your reflection coefficient with the
output port terminated by a mismatched load. There's
your conceptual error! The reflection coefficient, s11,
at the source is *NOT* the same as the reflection
coefficient at the load.

Have you told anyone else that an emitter follower with
a 450 ohm resistor in the emitter circuit will eliminate
reflections on all 450 ohm transmission lines?
