From: Jim >I recommend viewing/getting ahold of some of the old >Motorola "RF Device Data" books for a good feel on >how the RF guys spec devices. Good luck finding them. They have many good app notes, but you can find many good app notes from the many excellent online and user-freindly web sites from Siemens, Phillips, Harris, Zetex, et. And RF design & smith charting software too. Checkout http://www.rfglobalnet.com for software, tutorials, app-notes and website indexes. The last time I tried to get an app note from Motorola (several years ago), I had to have it faxed to me and it took 1/2 hour! I have found them unfreindly in several ways, which I'll refrain from detailing as they have been ranted about in this forum in the past, especially regarding getting their parts. It was said they are made from pure 'unobtainium'. Maybe they have to see if you are 'in the club' before they can sell to you? I don't know. >Another choice for some apps requiring RF amps/oscillators >are the family of products by www.minicircuits.com Their MMIC's or VNA's have constant 50 ohms in and out over their bandwidth, so its a no-brainer, but for the layout. And those suckers run hot and are inefficient. No substitute for good design, but cheap'n dirty.
