The problem I am having is when I apply transixtor square wave signal above KHz. Glossary of Microwave Transistor Terminology Text: Transistor Structure Typestransistor action. C B E the test assumes a model that is simply two diodes. RF power, phase and DC parameters are measured and recorded. You will see a practical test circuit for testing switching performance of the transistor.

See my answer for more details, but note that eg you have changed the oscilloscope settings between readings without telling us, and you show an “input signal” AT the base when in fact it is not a pure “just right” base drive but has characteristics of its own that probably matter, AND we do not know full details of how you measured what we see – and this too matters.

It can avoid transistpr the transistor into saturation, and it can actively drive the base low, not just leave it floating, to turn off the transistor.


The various options that a power transistor designer has are outlined. Sign up using Facebook.

Base-emitterTypical Application: But, this difference may be accounted for by your probe calibration. Did you change them between displayed results? Doctorslo 80 1 1 9.

If you apply a “perfect” low frequency square wave to your probe, such as is often available on a calibration pin on your oscilloscope’s yransistor panel, does it appear hransistor a perfect square wave, or does it have a rounded leading edge?

The transistor is not following that fast. But note too that you have “hidden in plain site” several things that need to be known for a really good answer to be possible. You are saturating the transistor.

It is likely that the circuit itself is swamping all these effects, but they start to come potentially significant at this level. When you change from the kHz signal to the kHz signal the waveform occupies 2 divisions in both cases. If the probe does not let you display a square wave response to a low frequency square wave then it will mask the results at higher frequencies.

The circuit driving the base can help with this in two ways. Have you calibrated your oscilloscope probe? Output at kHz of input signal: Transistor U tilization Precautions When semiconductors are being used, caution must be exercisedheat sink and minimize transistor stress. The molded plastic por tion of this unit is compact, measuring 2. Sign up or log in Sign up using Google.


Transistor Q1 interrupts the inputimplemented and easy to expand for higher output currents with an external transistor. Figure 2techniques and computer-controlled wire bonding of the assembly.

In data sheet it says MHz transition frequency. Then other reason is, you are using a very high collector resistor. The transistor characteristics are divided into three areas: In way of contrast, unipolar types include the junction-gate and insulatedgateof transistor terms commonly used in Agilent Technologies transistor data sheets, advertisementspotentially ambiguous due to a lack of terminology standardization in the high-frequency transistor area.

We shall limit our discussion to the horizontal deflection transistorat frequencies around 16kHz.

Non-volatile, penetrate plastic packages and thus shorten the life of the transistor.
