BFR91A 데이터시트(PDF) – List of Unclassifed Manufacturers

I would guess that general purpose transistors might work for T1 and T2, but T3 would need to be a wide band RF device. RF amplifier up to GHz range.

Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more A small current entering the base is amplified to produce a large fatasheet and emitter current. Look this one first- www.


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. Click here to register now.

Its maximum allowed heating is only mW but the max allowed heating is mW for a newer 2N An old 2N is in an old metal case.

Calibration equipment Electrical calibration equipment Pressure calibration equipment Temperature calibration equipment. In contrast, unipolar transistors such as the field-effect transistors have only one kind bfr911a charge carrier.

Power Dissipation Pd [Tamb. For a better experience, please enable JavaScript in your browser before proceeding. Not sure the will cut it: Replacement Transformer Started by ncag Today at 7: Willen Well-Known Member Jul 15, If the original project has an output of mW then with the general purpose transistors its output might be only 50mW.


BFR91A Datasheet

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and datasheeg. A 2N has better high frequency gain than a 2N but both have much less gain than the microwave transistors in the original project.

Observe precautions for handling. A 2N in the output should increase the power OK with a heatsink. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Willen Well-Known Member Jul 16, I haven’t used them for about 46 years but they probably still work. The 2N is OK.
