I'm in possestion of 4 LMX2326 PLL IC's and I'm looking for projects
to use them in.

I was thinking of building and designing an RF Signal Generator but
I'm confused about the VCO. Is it possible to use the LMX2326 to drive
a VCO built up of discrete components or do you have to work with an
VCO IC like the ones from minicircuits?

Hey OM:

Sure discrete is ok, you are going to use GaAs fets i assume? The
caveat is feedback the correct signal level to Fin or NOTFin.

I'll be using FET transistors, or experimenting. It's a learning
project anyway since I'm heading into microwave terrority next year
for my Master' degree. And I thought I'd get a head start by building
and designing some projects such as PLL driven VCO.

I'm now just looking for a good book on oscillator design. Any
suggestions?

Hey OM:

Nothing like a book to use for information like this.
I would point you to Electronic Design News. The monthly rag that has
plenty more up to date articles and information with footnotes.
There's cornucopia of info just in the footnotes alone in every
article.

I remember one article, I like to catch so called knowledgeable people
with: a modulation domain analyzer. Nobody ever heard of it, one of
the best tools ever invented. Is what an spectrum analyzer is to a
time based sweep scope: as the modulation domain analyzer is to a
spectrum analyzer,

I'd say there are some good oscillator design books out there, and
there are also lots of articles from various magazines. "RF Design,"
"Microwave Journal," and "Microwaves and RF" all come to mind. I know
that Ulrich Rohde has written some good articles on the subject. He's
also written books on the subject, like "Microwave and Wireless
Synthesizers." Dunno how good the book is, but I do respect the
author. Seems like I have some photocopies of decent VCO articles out
of "Wireless World," too.

Continuing the basenote drift: Dunno if it was ever marketed
specifically under the name "modulation domain analyzer," but the the
HP89410 series of Vector Signal Analyzers is extremely good at that
sort of thing. The Agilent 89600 series is likewise very good at
complex analysis tasks.

Cheers,
Tom

A book that was recommended to me just a couple weeks ago is "RF and
Microwave Transistor Oscillator Design", Grebennikov (Wiley, ISBN
0470025352). I haven't ordered a copy yet, but the recommendation came from
a very knowledgeable designer.

I just bought that book by Grebennikov not 24 hours ago. I've quickly
scanned it through and it's a worthwhile addition to the library. It's
a little heavy on the math but has great examples and design
exercices. A serious knowledge of transistors and electronics is
required before starting in this book. Biasing and S-parameters aren't
explained (references given though).

And PCB layout isn't handled either, this is something of a drawback
if you ask me.

I'll be on the lookout for Ulrich Rohde's book.
