Default Low distortion HF rcv preamp?

Hi all,

I'm interested in finding out what the state of the art is in low
distortion preamps for HF receiving systems. Anyone out there have
pointers to reasonable designs for a preamp with input IP3 above, say,
+55dBm, with amplifier power requirements limited to half a watt, and a
noise figure better than 10dB? IP2 should also be high--greater than
+100dBm--though it may be acceptable to have a lower IP2 as frequency
increases. Gain around +10dB would be good.

Cheers,
Tom
