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

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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
