Can anyone summarize the differences between the NE602 and the NE612 Double-Bananced Mixer and Oscillator chips from Signetics. I have the "Linear Data Manual Volume I communications" from Signetics. The documentation on these two chips seems almost identical. The specs are all identical (Wherever they give comparable specs for both chips.) If I have a design that calls for the NE602, can I substitute the NE612? (say in a simple direct conversion receiver.) Thanks for helping to clear up the confusion. David Adams dadams@cray.com

A note from a Signetics engineer in Technical Correspondence or Hints & Kinks
in QST within the past year or two mentioned in passing that the NE612
was a lower-performance version of the NE602. If you look carefully at the data
sheets, you'll notice that the NE612 has lower gain (figure 11 on both sheets),
by about 4 dB.
Keep a look-out for the NE602A, which has an improved intercept point.
