Hi guys,<br><br>Now some of you might not be jumping up and down at news like this, but I sure am. I just scored 50 2SC2570As. They are a UHF/VHF Low-noise amplifier NPN BJT....They are for small signal, like preamps in receiver front-ends etc.<br>
<br>Now, on eBay this little baddies around going for $1-$3 dollars a transistor plus shipping. I managed to score a whole lot of 50 of them from some obscure distributor somewhere for $0.30 cents a pop. <br><br>They have awesome figures. <br>
<br>@ 1GHz they exhibit a gain of 8dB w/ a NF of 1.5dB<br><br>@ 100 Mhz they have a gain of around 25dB and should have a NF of < 0.5dB<br><br>And the best part is - they aren't some really finicky easy to kill extremely expensive GaAs FET....<br>
<br>WIN !!!<br><br>;-)<br><br>Here is a link to the datasheet in PDF format:<br><a href="http://www.datasheetcatalog.org/datasheet/nec/2SC2570A-T.pdf">http://www.datasheetcatalog.org/datasheet/nec/2SC2570A-T.pdf</a><br><br>
I can see lots of mast mount preamps being designed, tested, and produced for every freq band for the whole crew :)<br><br>73s de W1QEX<br><br>
