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 nice lady's voice announced "You've Got Mail" when a new message arrived...

Noise Figure of a SAW Filter - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

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

Post subject: Noise Figure of a SAW Filter Posted: Fri Oct 14, 2005 11:51 am
Good day. I was given a receiver design that uses two SAW filters from Sawtek (856327 and 854656). I need to do a noise figure analysis for the receiver and I am a little confused about how to handle these filters.

I have contacted Sawtek and they were not able to provide me with any data. Also I do not have access to these devices so I cannot measure them.

Does anyone have any suggestions about where to find information about this (website, book, magazine article, etc.) ?

I am using Microwave Office for the simulation.

Thank you for your time and help.

Michael

The NF is basically equal to the insertion loss at any given frequency, but it must be measured at the input/output impedance used with the SAW device.
