I will have a look but I am not hopeful as the problem was that Mini circuits use the thinnest Rogers substrate
available to do the impedance matching which few board houses stock. It worked out at about £100 per
board. It has been suggested I could use FR4 instead and live with the losses. It was also suggested that if
I bought 250 boards I could get the price down but I am not really in the business of selling stuff.
The AVA-183A+ chip from Mini-Cicuits is good from 5 GHz to 18 GHz with a flat gain of 14dB across that range
and a P1b of 19 dBm @10 Ghz falling to 18.7 dBm @ 18 Ghz. The devices cost $9 each.
Useful little gain blocks
Not sure quite what spec you want but would a couple of MMICs cut out of a Franco board do the job?

These are great valuse of money and have been used all over the place - you just cut them out with a pair of scissors and all the hard work is done!
I have some of those but they don't provide enough power to drive the 10 Ghz
double balanced mixers I have. I had thought of trying to use one as an
active mixer that would remove the need to use the diode mixers. I have just
not got around to it yet.
My application is for Metrology which has slightly different requirements to
a receiver in that I need to have a number of phase matched outputs with good
return losses, which means splitters and attenuators which all loose power.
I am slowly collecting eBay bits when I see them at good prices.
Got a quick delivery on it from China - just 7 days - sent by air mail. The original one I got took weeks to arrive.
