Hi John,
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
