Noise Figure of a SAW Filter - 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.

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.
