1 Watt UHF Amplifier schematic wanted

[Diego Stutzer]

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: abcdstutNOFRICKINGSPAMzer@evard.ch

Thanks in advance.

NOFRICKINGWAY. It's considered rude to ask for replies by email. Shows
you're too fricking lazy to check back in the newsgroup for replies.

Thanks in advance.

----------------(from OED Mini-Dictionary)-----------------
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).

From a fully deputized officer of the Apostrophe Police!

I bought some batteries, but they weren't included,

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

[Now why do both Lizzard Blizzard and Allodoxaphobia sound like Dark Matter?
I think the case is just being made stronger daily for a minimally moderated
newsgroup.]

www.rfparts.com

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.
