RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Please help to identify the transistor (or amplifier) - RF Cafe
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

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
The components are used inside voltage control oscillators
(VCO) designed for high frequencies (4 - 6 GHz) and for 1 GHz bandwidth
Every VCO has only one of this component.
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
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

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