Substrate for LNA

My question is that what type of microstrip substrate usually used for LNA at s band frequency range.Please mention me of DUROID.
 

Substrate for LNA

hi ahmad i use duriod 5880 of 2.2 epsr and thick of .7874mm(.031 inch),i think it is quiet cheap and available
 

Re: Substrate for LNA

Yes.. duroid, Arlon , Cuclad. You can found some manufacturers, the importand need of a LNA is that the material has low lost. So you must found a compromise betwen price and features... depends on your aplication..
 

Re: Substrate for LNA

:? How about TEFLON boards, anybody has used it.
but price is highest

Hi Ahmer Saeed,

Since you are mentioning about DUROID, you could also look in to 5870. It has a little higher Er & tan loss compared to 5880.

Up to 2GHz FR4 (if there isn't special purpose) above 2GHz RO4003.
 

Re: Substrate for LNA

5880 is suitable for design of LNA.
I designed some LNAs with 5880 and found it very excellent!

I think RO4350 or RO4003 is OK and price is cheaper than Duroid 5880. I used R4350 to design LNA at S-band and the noise figure measured is 0.85dB......

above 2GHz RO4003.

above 12GHz RO5880.
