Quite by accident, in leafing through K9AY's new magazine I ran into a 
reference to a surface-mount PIN diode 
<http://www.skyworksinc.com/Product.aspx?ProductID=857> designed 
specifically for receiver protection.  It begins to block signals at +10 
dBM, and works by quite a different mechanism than conventional diode 
limiters, resulting in pretty high IP3. The specified lower frequency 
limit is 10 MHz, but I wonder if that is arbitrary

Has anyone tried this approach to receiver protection on Topband?
