Hmm, yes and no. Yes, that's the idea - but no, don't buy it from that person - the chip only costs $12.10 http://www.linear.com/purchase/LTC5544 Also, there's the http://www.linear.com/product/LTC5548 which goes from 2 GHz to 14 GHz with an IF of DC-6 GHz also - and costs $13.58. Enclosed is an image of the demo board which costs $125 for the LTC554 and $200 for the LTC5548. Considering that the chip looks like it might fit inside of female SMA connector, the demo board might be worth the cost. You can also use them as an upconverters. -- Cinaed > > On Fri, Jul 15, 2016 at 3:27 PM, John Wright <[email protected] > <mailto:[email protected]>> wrote: > > I would love to try a 4-6Ghz downconverter.
