Limiter

A limiter is aelectronic device used to limit the amplitude of a signal within a certain range to prevent signal overload or distortion. They work by applying a variable gain to the incoming signal, reducing its amplitude when it exceeds a predetermined threshold or limit. Limiter is a self-controlled attenuator and a power modulator. When the input power of the signal is small, there is no attenuation. When the input power increases to a certain value, the attenuation will increase rapidly. This power value is called the threshold level.

The characteristics of our RF limiter include:

1.High speed limiter: can respond quickly and process high frequency signals, so that the signal is kept in a safe range.
2.Low distortion: can effectively control the amplitude of the signal, to ensure that the signal will not appear distortion and damage.
3.Broadband characteristics: frequency coverage 0.03 ~ 18GHz, can process a variety of frequency signals.
4.High precision: the amplitude of the signal can be accurately controlled to ensure that the signal processing is as accurate as possible.
5.Low power consumption: the power of 5 ~ 10w is mostly, making them very useful in high-frequency applications under the constraint of mobile power supply.
6.High stability: The beam can maintain stable performance under temperature changes and other environmental conditions, so it is very suitable for complex applications.

The following are some applications of limiter:

1.Protect circuits and devices: Limiter can be used to protect circuits and devices from high signal amplitudes. When the input signal exceeds the limit threshold, the limiter will limit the amplitude of the signal within a safe range to prevent signal overload and damage to the device.
2. Audio processing: Limiter is widely used in audio processing. For example, in music recording and playback equipment, limiter can be used to control the dynamic range of the audio signal, so that the amplitude of the audio signal is within an acceptable range, preventing audio signal overload or distortion.
3. Communication system: In the communication system, the limiter can be used to adjust the amplitude and dynamic range of the signal to ensure that the signal does not exceed the signal-to-noise ratio limit during transmission, improving the quality and reliability of communication.
4. Video processing: Limiter is also commonly used in video processing. For example, in video cameras and surveillance systems, limiter can be used to control the amplitude of the video signal, so that the brightness and contrast of the image are within the appropriate range, improving the clarity and visibility of the image.
5. Precision measurement: In some precision measurement areas, the limiter can be used to control the amplitude of the input signal to ensure the accuracy and stability of the measurement results. For example, in high-precision measuring instruments, limiter can avoid measurement errors caused by out-of-range input signals.
