In one old fujitsu monitor video stages, I found 3 1,2ghz hitachi wide band transistors 2sc, 4pf capacitance. Sorry about the confusion, but my original comment was about availability of the 2SCs, not about quality or suitability for the task.

As to 2wc1815 2SC, I do have a good quantity of them and it is a very good and useful device. Low-cost on board temparature sensor Calibrated directly in oCe.

It works, well packaged, will order again.


While the 2n maybe a rough call due to origins not all are good quality the 2sc is not suitable for the bidirectional amplifiers without paying close attention to applied bias and collector load impedence. It has a mw dissipation and can switch ma. Most of our products are new and original, any interests please contact me. Get the latest updates on offers and promotion 2. As Farhan has stated several times, the gain for each stage is fixed by the feedback, not by the particular device being used assuming it has enough gain at operating frequency to function properly in the BITX design.


Looking at the curves the device is also optimized for 6V applications. This is not temperature compensation. It has tons of cool. Martin French part St. Search Only Within This Topic. The inherent stability and hence the reproducability of the BITX is due to the fact that transistor types dont matter much, and the negative feedback assures that the individual stages dont self-oscillate.

There will still be drift from warming or cooling of other components. It only one of many I chose from for various projects. Sunamura san has referred to their being readily available at reasonable prices in some of his writings, and thus the reason for them appearing frequently in his homebrew projects.

The second pf capacitor from emitter to ground collector is at RF ground due to the. Often this is easily found by using a LM variable voltage regulator and starting at the design voltage and noting startup drift. There is also several wats output video amplifier transistors 2s by sanyo ft mhz 2,7 pf capacitance 8w.

2SC1815 – 2SC1815 NPN Small Signal Transistor

I used to take advantage of this ways back when transistors capable of HF or low VHF were very hard to get. Then by adjustment of the voltage to the VCO it’s possible to reduce or even eliminate that drift. Get the latest updates on training, seminars, and workshops.

Noise figure is 4db at audio. I was referring to the fact that the 2SC is very readily available in Japan It is even more plentiful and readily available there than the ubiquitous 2N is in other countries. Add to Wish List Compare 2sd1815 Product. I have an unusually good selection of new devices as I used to provide service in commercial space for a variety of electronic gear.

Your email is included with the abuse report. The 2sc is a 80mhz Ft at 1ma and increses to at ma. Also most metal can transistors often ehhibit higher capacitances as a side effect of the much higher power dissapation capability.

What is Students Benefits Program? While they are usually of quite high quality, I suspect the main reason that Sunamura JF1OZL uses so many of them is that they are plentiful and relatively inexpensive.

The 2n is a mhz Ft with a mw power dissipation and can switch ma. This gave lower capacitance and noise than usuall transistor technology.
