RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

sawtooth generator - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

I was wondering if there was anyone
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

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?

in the megahertz range

That's still not very specific. What's
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.
probably goes beyond 50 MHz
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.
