LNA (equivalent noise resistance parameter) - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi,

I'm using the following transistor for an LNA design:

http://www.semiconductors.philips.com/pip/BFG520W.html

I can get the s-parameter blocks from the website, but don't know what to use for Rn - the equivalent noise resistance parameter. Does anyone know how to read this off the datasheet? (say for 900MHz)

Some vendors give noise data at the end of the .s2p files, e.g. NEC do. Philips obviously don't.

Thanks
