[hpsdr] Phoenix to Janus balanced driver

[Christopher T. Day]

Is anyone else on this list missing the original message to which the
below is a reply? I seem to have missed several on the Phoenix threads,
at least, for some reason.

Thanks for keeping this all INTERESTING... I'm a googler.... What
characteristics are you looking for in this part? Gain? Slew rate? 2nd
or 3rd 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"?

I've just added a sample schematic to the Phoenix Wiki page (
http://hpsdr.org/wiki/index.php?title=PHOENIX )  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.
