  1. Hi again,
    I'm looking for a schematic of a uhf-amplifier with a gain of about
    10. It shoud give about 1 W output power (to a 50 Ohm Load) at about
    100mW input at the (preferably 50 ohm) input (impedance).
    The frequency to be amplified is about 440-450 MHz.
    Please post links to circuits matching my requirements and generally
    all uhf-amplifier design related links here or send me schematics via
    e-mail:

    Thanks in advance.

    you're too fricking lazy to check back in the newsgroup for replies.

    PUNCTUATION - Apostrophe
    Incorrect uses: (i) the apostrophe must not be used with a plural
    where there is no possessive sense, as in ~tea's are served here~;
    (ii) there is no such word as ~her's, our's, their's, your's~.

    Confusions: it's = it is or it has (not 'belonging to it'); correct
    uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
    but ~the dog wagged its tail~ (no apostrophe).

    I bought some batteries, but they weren't included,
    so I had to buy them again.

  3. Ha!
    So, maybe you think the spam harvesters will ignore your
    un-munged From: in your posting?

    buy a motorola or similar RF module. aka a "CATV Brick" or "CATV
    AMP".

    cost 60-90$ US.

    usually runs off 12 or 24 volts, and get the app note/manufaturers
    data from RF parts

    make sure you have a good RF wattmeter and adjust the source before
    the amplifier to avoid overdrive. overdrive is BAD. It will need a
    heatsink!

    if your really transmitting with it, put a filter on the output as
    many of those modules have bandwith from 0 to 550 mhz or so. The law
    says any harmonics and spurs you generate must be about 40 Db down
    from your output


    time spent building anything else without the proper equipment,is
    priceless, and judging from the language in your post, you dont have
    the skills/milliwatt meter to do it.

    Dont expect this fowarded via email.
