So, what does this mean to the rest of us?
"The mixers using 1N914/4148 diodes are not level 7 mixers (nominal 7dbm drive) like commercial DBMs.
the reason for this is Schottky diodes have a lower turn on threshold than silicon junction diodes with the difference being .2V compared to .65V. This means you need more LO drive for the terminal impedance
of all ports to be 50 ohms. It also means they are higher level mixers by about 3db. So enough drive is important to intermod and overload." - Allison
Is this the part where Tom W5KUB "solved" the low TX power problem with taking the SMD dual diode off and replaced it with two regular diodes? It did seem to make a small difference. But not with the 1N60. Only after changing it again with 1N4148.
Is this what she is talking about here? I am not an engineer. So, is it saying lower turn on threshold helps driving the PA? Or is it higher?
