Hi All,

I was reviewing a 75 to 50 ohm resistive matching network using two resistors,
the insertion lost was 5.7 db.

Hi OM,

Snips
However, this is not the best design for a
matching network, they are usually three resistors in either a PI or T
configuration.


Several manufacturers of precision matching pads might disagree!
Two resistors is enough, although you have to remember to add a rather
odd number (unless the measuring equipment can add it for you). If you
add a third resistor, you can make the correction a straight 6dB. That's
probably the only virtue.
