    E-plane waveguide junction

    There is a good article in IEEE Microwaves and Theory Transactions about 4 years ago. I don't have it with me, but you should be able to log onto IEEE.ORG and search the Microwave Theory area (MTT) for waveguide diplexers and come up with it. Good Luck - Bob Griffith (author of eSeptum)

    What is the Best CAD for microwave layout?

    I use AutoCAD... but more recently a package called &quot;ProEngineer&quot; has become popular. For mechanical layouts, &quot;Solid Works&quot; is being used a lot. <br> <br> Most of the more popular PCB programs will import DXF files from AutoCad directly. <br> <br> Hope this helps..<br> <br>...

    WHY is software so unmanagable?

    Interdigital Capacitors

    Yep... I have built capactors up to 38GHz using interdigital designs.<br> <br> You can design you own for free using a download from Sonnet Software. They have a FREE EM Simulator (limit in problem size, but plenty big enough for ID Caps).<br> <br> Try them out at http://www.sonnetusa.com<br>...

    Analog Design?

    Yep... being a "Real" RF Engineer of 25 years, I get a bit disappointed in the the current design trends of "Plug and Play" circuits. At this rate, all the "REAL" rf design will done done at MMIC facilities and Foundries. I also host a web site for RF Types... www.engineers.com Or...
