I started with the manufacturers application note loaded the values into Puff then scaled everything for the lower frequency, then modified the values until I got the expected gain and match. I then had to modify the actual circuit to reproduce the 'ideal' results predicted by Puff. The gain was measured using a Gigatronics power meter. The input return loss was not as good as I had hoped but it should be good enough.G4GUOhttps://www.blogger.com/profile/15634884412587660320noreply@blogger.comtag:blogger.com,1999:blog-6865153472775099637.post-88357265829922183512011-03-25T18:01:24.490+00:002011-03-25T18:01:24.490+00:00Hi, I consult that software used you to design mat...Hi, I consult that software used you to design matching networks in and out, because I've used Smith Software and I did not get results, I only get 6dB gain @1300MHz.<br />Thanks<br />JosueJosuehttps://sites.google.com/site/proyecto900mhz/noreply@blogger.com
