LNA (equivalent noise resistance parameter) - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
