Thank you,Vasile.  That site is very useful.  Actually I am looking for 
components above 40 GHz and even above 100 GHz.  I also need to get into the 
T-ray band. GaN devices can achieve this but I do not know of anyone 
producing them commercially.  But I can make good use of the information you 
sent.  Thanks.
