Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

If you mean is there a good application for a
VCO the smartass answer is yes: an oscillator where the frequency is
Did you mean "do we know of any design application
notes to help design these", then about the best source of articles
I know of is by Ulrike Rohde.
If you google his name then it should
biff back some good papers he has written.
He now runs a US company
making a wide range of integrated assemblies for mixers amps and VCOs.
So he has found another good application for VCOs: making money.
All power to his elbow (as we say over here). I thought the days of
successful microwave companies run by excellent microwave engineers
had long passed.

I thought your VCO was so good people would create application
just to use it.
More power to your thumb knukle I always say...here....in
my cubicle...all alone....with my empty rfcafe coffee cup...the sound
of engineers laughing at me...
You could always try Skyworks
for some app notes.

The company I was trying to remember is Synergy Microwave.
They have design app notes on their website at synergymwave.com.
Hey Yendori: I should be so lucky. My colleagues laugh at me
because one of them stole my RFCafe mug. How about that. I knew the
mugs were valuable but I never imagined someone would stoop to stealing

I understand about the coffee mug problem. The thing is it's more than
a coffee cup, it tells the world that "I know Kirt Blattenberger!"
Engineers sit in a circle in the lab while I tell stories about
Kirt. I say his website has more links than grains of sand on the beach
and although he is only 5 feet tall he can squat 600lbs. Kirt is a very
handsome man yet he still felt it neccessary to PhotoShop out some blemishes
on his home page picture. Kirt makes a mean glass of lemonade.
Then everybody takes a sip of non fat milk from the RFCafe mug and
gets back to there Spectrum Analyzers with envious, but satified grins
on there faces.
Sorry Nubbage, I need a vacation
