<DIV>Looks like things have moved along a bit. The latest Kuhne 2mtr
transverters use a high-level triple-balanced GaAs-FET ring mixer
with an IP3 of >35 dBm.</DIV>
<DIV>I cant find any links to gas fet rings, anybody any suggestions???</DIV>
<DIV> </DIV>
<DIV>Of course all this assumes that the tx 14bit DAC is clean enough for
the LO ???</DIV>

<DIV><BR></DIV>I use the Kuhne xverters as they are robust and I assume being
from Germany they can handle the EU contests.
<DIV>Only down side is that they are pricey.</DIV>
