Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Please help to identify the transistor (or amplifier) Posted: Thu Aug 23, 2007

I need help in identifying the following transistors/amplifiers (see links to the photos below). They
differ only in the marking (on the first the marking is "2n" and on the second "2i" or "2t").
I've tried to search according to the marking
ana have not find anything.
The components are used inside voltage control oscillators (VCO) designed for
high frequencies (4 - 6 GHz) and for 1 GHz bandwidth each.
Every VCO has only one of this component.
The VCO is a regular Colpitts oscillator and the component (I'm trying to find out its P/N) is actually the
transistor used to provide the negative resistance.
As could be seen at the photos the component has four
leads, one of them is not used. The other three are used as Emitter, Collector and Base of bipolar transistor.
I need the manufacturer of these parts and part numbers if possible.
I will appreciate your help!

It is very difficult to idetify
You must try to give us more information.
I know some transistors has more details in
there side like these example :
