Power of Burst waveform going through an amplifier

In summary, a Burst waveform is a type of signal that consists of short pulses followed by no signal, with a high peak power and short duration. It differs from a continuous waveform, which has a constant amplitude and frequency. The Power of Burst waveform is significant because it determines the maximum power an amplifier can deliver, making it useful for applications such as medical imaging, industrial material processing, radar systems, and communication systems. However, the high peak power of Burst waveforms can potentially damage amplifiers, so they are equipped with protection mechanisms to prevent this.

Hi all,


How would I calculate theoretical power of:

1Vpp
1Mhz (sinewave)
200 cycles
100ms interval
50Ω load

This waveform is going into a 55db amplifier.

Any help would be great.

Thanks,
Mark

1Vpp continuous into 50 ohm is 2.5 milliwatt.
2.5 milliwatt for 200 cycles at 1 MHz is 0.5 x 10^-6 joule.
0.5 x 10^-6 joule 10 times per second is 5x10^-6 joule/second or 5x10^-6 watt.
(5 microwatt)
 

1. What is a Burst waveform?

A Burst waveform is a type of signal that consists of a series of short pulses, followed by a period of no signal. These pulses have a high peak power and short duration, making it useful for applications that require high power but low average power.

2. How does a Burst waveform differ from a continuous waveform?

A continuous waveform, as the name suggests, is a signal that is constantly present. It has a relatively constant amplitude and frequency. On the other hand, a Burst waveform has a non-continuous nature, with short pulses of high amplitude and frequency separated by periods of no signal. This results in a higher peak power for the Burst waveform compared to a continuous waveform.

3. What is the significance of the Power of Burst waveform?

The Power of Burst waveform is important because it determines the maximum amount of power that can be delivered by an amplifier. This power is directly related to the amplitude and frequency of the waveform, and a higher Power of Burst waveform means a greater capability of the amplifier to deliver high power signals.

4. How does an amplifier handle a Burst waveform?

An amplifier is designed to amplify signals, regardless of their waveform. However, when a Burst waveform is passed through an amplifier, the high peak power can cause damage to the amplifier. To prevent this, amplifiers are equipped with various protection mechanisms to ensure safe and efficient operation with Burst waveforms.

5. What applications benefit from the Power of Burst waveform going through an amplifier?

The Power of Burst waveform is advantageous for applications that require high power but have limitations on the average power. This includes medical imaging, industrial material processing, radar systems, and communication systems. The use of Burst waveforms allows for increased efficiency and accuracy in these applications without damaging the amplifier.
