who knew how to make a very high frequency sawtooth generator, or possibly
very clean high frequecny pulses to discharge a cap for sawtooth generation.
everything i have tried is unaccecptable at the frequencies i am interested
in.

Um, how are we going to
help you if you are having trouble at "the frequencies i am interested
in" if you don't tell us what those frequencies are?

so hard about naming your frequency range? 1-10 MHz? 100-500 MHz? It
makes a difference.
Here's a Maxim MAX038 waveform generator
circuit for up to 20 MHz. http://www.maxim-ic.com/appnotes.cfm/appnote_number/650
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1257
This circuit
probably goes beyond 50 MHz http://www.elecdesign.com/Articles/Inde

The best thing to do probably is call some of
the IC vendors and talk to an applications engineer. They'll know right
away if they have a solution, and the advice is free.
