KD5NWA: The transformer seems simple enough, especially with a fixed mixing frequency. I found it being used with a vfo for 40 meters and it does look allot like a balun or transmission line transformer. I got an email on a file to check out a twisted pair idea here today.
Also, there is way to split a signal off into two for I Q with a resistor in one line, equal in resistance to either a capacitor or inductors reactance in the other line. The reactance's phase shift voltage and current by 90 degrees in the one line. It appear that a single capacitor or coil in the other line will shift ther pahse 90 degrees but only if the frequency of operatiuon is fixed or limited.
