    Hy,
    I need a little bit of tutorial on coaxial transfer switch and more
    generally on transfer switch, on google I searched a lot but still
    haven't found what I'm looking for, I mean theory on schematics and
    materials. Any of you know where I can found such kind of information
    ??
    It's for my Master thesis. Many thanks

    yes,
    "Coaxial Switch Theory" = 0 results
    Coaxial Switch Theory = 221000 results regarding vendors of switch,
    theory in general and coaxial everithing, semantic search id something
    different.
    Thanks the same John

    Well I wouldn't expect to find much useful on that through Google at
    such a general query level. Also, library search or a search on IEEE
    Xplore would probably give you much better info. Maybe your thesis
    supervisor can give you some references to check? For example you could
    check one of the microwave, filter etc books written by David M. Pozar.

    If you know the details of what you're searching for, for example RF
    microwave PIN-diode SPDT switch, you might be able to find documents
    over Google, but an overview is probably hard to et.

    One hit for "microwave spdt pdf" (without quotes) was

    http://www.plextek.com/papers/Discrete PIN SPDTs and SP4Ts.pdf

    and you can see also the coax connectors there... ;-)) Those are not
    mechanical switches, though.

    You could also check the Philips RF Manuals on
    http://www.philips.semiconductors.com/products/discretes/documentation/rf_manual/
    though I'm not sure if they contain anything on transfer switches
    specifically.

    Looking on www.amazon.com for transfer switches gave this one
    http://www.amazon.com/gp/product/0471201693/002-5976338-5908068?v=glance&n=283155
    "RF MEMS: Theory, Design, and Technology" Could be good, if MEMS is what
    you're looking for. Maybe your library has it.

    The "coaxial" bit in "coaxial transfer switch" means just the connector,
    AFAIK, and basically it could be any other type of transmission line
    too. So you might be better off searching for the internals of transfer
    switches (mechanics, electronics) instead of the packaging and connector
    types. Of course, I don't know what exactly the subject of your thesis
    is... :)

    Actually...

    just noticed the references at the end of:
    [2] Street, A.M. “RF Switch Design”, Proceedings of the IEE Tutorial
    Colloquium on “How to Design RF Circuits”, April 5th 2000, pp 4/1-4/7

    That could be one further lead.

    Try this:
    http://www.estec.esa.nl/conferences/03C26/papers/a022.pdf

    It was the third hit on my Google search using
    "Coaxial Switch" theory
    in the search box.

    There *have* to be others - just look.

    MaCom (http://www.macom.com) have excellent papers on RF switch theory
    for PIN devices (I use a couple of their switches in a current design
    partly *because* they have excellent explanatory papers apart from
    being good products).

    Cheers
