Hi,
It sounds like all my messages need moderator approbation. Is it the
rule on the list or a technical problem at my side ?
Cheers
Stephane

Hi Stephanie,
Welcome to the list!
We designed a 1GHz crystal LO for PLLs (the ULN-1G) using an off the
shelf miniature 500MHz crystal oscillator which is run at 3 rd
overtone internally then using a diode doubler and a steep bandpass
filter using several Mini Circuits ceramic filters and a 20dBm amp.
Works like a charm and has phase noise very close to theoretical..
Bye,

Hi the list,
Just wanted to introduce myself for my 1st message.
I'm Stephane, 40, living in France, at the moment working in RF &
electronics for a particles accelerator lab. I'm hamradio as well, and
I do enjoy especially weak and accurate signals.
I'm desiging various RF circuits. Current design is a universal PLL
able to operate from 0.5 to 6 GHz depending on the VCO and supposed to
be "low-jitter" (<1ps) regarding the application.
I'm also starting a new design of low noise PLL and there will be
probably a lot of question arising... I'm starting with the 1 GHz LO
made upon a 100 MHz VCXO + multipliers/filters/MMICs.
I want to focus deeper on low phase noise/jitter, synchronization
and low-noise PLL techniques.
I believe this is a good place for most of these topics.
Cheers
Stephane
