Because the controlled output power bfra be higher than the controlling input power, a transistor can amplify a signal. A 2N in the output should increase the power OK with a heatsink. Power Dissipation Pd [Tamb.
I still have some old BC transistors in the same old metal case as an old 2N If the original project has an output of mW then with the general purpose transistors its output might be only 50mW.
These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. The customer is in the focus We want to make sure that customer is the center of attention.

I would guess that general purpose transistors might work satasheet T1 and T2, but T3 would need to be a wide band RF device. Willen Well-Known Member Jul 15, RF amplifier up to GHz range. Articles Top Articles Search resources. Its maximum allowed heating is only mW but the max allowed heating is mW for a newer 2N Thread starter Willen Start date Jul 14, The original circuit used good high frequency transistors but you are using ordinary “general purpose” transistors that might melt with a supply that is as high as 12V.
Now I have hundreds of PN datashset. Region Macedonia Kosovo Global.

A 2N has better high frequency gain than a 2N but both have much less gain than the microwave transistors in the original project. Collector — Base Voltage Vcbo. Bipolar transistors are so named because their operation involves both electrons and holes.
The 2N is OK. Free technical support If something goes wrong, we will be ready and willing to help! There is no point, i feel, inchanging devices for the sake of changing. In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. I have never seen nor used one. Observe precautions for handling.
