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...

High Performance RF Front End, Selectivity + Overload - 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.

Hello,

We are working on a design for a high performance RF Front End for a digital FM Reciever. The end system will perform many various RF processing techniques using a Xilinx FPGA device.

That being said, we have some specific criteria to meet on the RF Front End

Such as - sensitivity down to 1-5uV range at the frequency of interest
Overload rejection of upto 12V for a blocking signal without densensing

There was as McIntosh reciever (MR-78) that was designed to handle such overload without the desensing effect.

Does anyone have references, schematics, etc for any various RF Front ends that could offer such overload rejection and/or references on how to develop such overload protection without the desensing effect?

The overload - without desensing - is the primary issue we are facing right now.

Thanks
