	Running at 200MHz, the third harmonic at 600MHz is only
	down -11.5dB, while the 5th harmonic at 1GHz is down -20dB.
	With a 20MHz output, the 3rd harmonic is -10dB and you have
	to get to the 23rd harmonic at 460MHz before you hit -30dB.

Uhm, this is actually a good thing.  The thing is supposed to have
a square-wave output, so all the odd-numbered harmonics have better
be there and have better follow the 1/N amplitude law...

Never attribute to malice what can adequately be explained by incompetence.
