Hi Bruce,

The filter you are referring to is the Neosid 120MHz filter - it is available from Eisch Electronik, http://www.eisch-electronic.com/
part no 511836.  It is specified as 120 to 160MHz, so not sure it will go down to 100MHz.  If you wish make an enquiry with Eisch, the proprietor, Uli, does speak English.

Hope this helps,
73

In an earlier post I mentioned that I had been searching on-line for ideas  
to multiply a 10 MHz signal to 100 MHz.  I would like to multiply the 10  
MHz outputs of an LPRO and a Thunderbolt GPS to feed to 10 GHz phase-locked  
microwave sources so their outputs can be fed to a mixer for enhanced 
frequency  comparison.

F4GBC kindly provided the following link for an article in French.

HI all,

have a lok to  :

After looking at the article I searched on-line for the part number of the  
specified 100 MHz filter and found a link to an English language version of 
the  article _http://g4hup.com/DFS/F9HX%20synthe%20english.pdf_ 
(http://g4hup.com/DFS/F9HX%20synthe%20english.pdf) ,  should anyone be interested.
