There is a very simple reason why there are no 'Whiz-bang' type Cube
sats.
POWER.  Power is everything guys. You have about 3 watts to work with
lets say you only used 2 on the transponder, (highly unlikely, a
transponder with  any width would leave everyone milliwatts of power)
that leaves you 1 watt for everything else. Attitude control, Processing
, Sensors etc.
I would like someone to find me a RF DSP and support chips  that could
process a whole
frequency band that uses about 1/2  watt!  For you neophytes thats 160ma
at 3v or
100ma at 5v.
