One thing I have not seen in the spec's so far is what the output level is.
Have you measured that or do you know what it is?
If I remember correctly the original version was in the -10 dbm range.

Joe,
I haven't gotten around to measuring the output levels. I'm not sure how accurate my power meter is pass 1 GHz. If it helps these are the levels that Gabriel has annotated on her schematic.
IN to OUT transmission: ?10dB
IN to REFL (OUT shorted): ?30dB
IN to REFL (OUT open): ?30dB
Coupling factor: ?20dB
I not sure if the -10dB IN to OUT transmission is really dBm or actual loss through the directional coupler. Most directional couplers I've used have less than a dB through loss.
