I don't have any TUF-1 mixers but I have a number of TFM-335 instead (Dayton 2008). I don't have a datasheet but I believe similar to TFM-3. Seems pin 4 is LO, 1 is RF, 2 is IF and others are ground.
I lashed together a test rig with the output to a spectrum analyser (USB Oscilloscope). Believe work with LO DC-100MHz (that is as far as DDS VFO will go, might go higher).
Please can anyone that knows these comment at all? Especially on the LO and Rf signal levels?
