I’m a googler…. What characteristics are you looking for in this
part? Gain? Slew rate? 2<sup>nd</sup> or 3<sup>rd</sup> distortion? I can search
with the best of em! Name your spec, and design the ISD! Is there a method of
posting on the wiki to allow ‘hot spots’ for pop-ups for the
components like “current isd”?<o:p></o:p></span></font></p>

page ( <a href="http://hpsdr.org/wiki/index.php?title=PHOENIX">http://hpsdr.org/wiki/index.php?title=PHOENIX</a>
) that illustrates a possible balanced driver that could be utilized to
feed the IQ signals from the ISD to the Janus balanced inputs. (The schematic
immediately follows the second block diagram). An LT1994 chip is illustrated.
There may be better parts to utilize in this position. The schematic
illustrates just the Q channel. An identical configuration would be present for
the I channel.<o:p></o:p></span></font></p>
