A HEO satellite with a 10 GHz downlink would be tons of fun. We've been
using these along with surplus DSS dishes using a Funcube as an IF to
create really cheap 10 GHz receivers that work well!

Watch the wrap...

However, to include operators with modest shacks, you need to allow
operation on modes A, B and/or J. A satellite operating on 24.0 GHz
won't be of interest to the average ham. Not until the average ham has
24.0 GHz capable antennas, feedlines, amplifiers, transceivers, etc, in
his shack.

Yea but increasing frequency helps with that. With directional
antennas the satellite would need attitude control which would benefit
greatly from miniaturization. For the most part, miniaturization would
come from incorporating systems on chips. Most op amps and
microcontrollers are much smaller than their packages so including
those systems on a single die in a single package are capable of
massive savings in space. This is what made smart phones even possible .

Let's put it in another possible context: Create an extremely
dense and reliable LEO platform in cube-sat form that weigh's
a fraction of AO-40's weight using today's high-density
components/systems and create a reliable and feature rich HEO
cubesat.
The only problem with this, is that certain components can't be
miniaturized. Example: Antennas. And HEO satellites need more
sophisticated antennas.
Pity the cube-sat idea didn't finish up with a ten INCH cube...
