What is a frequency multiplier?
Frequency multiplier is a device that creates an output with a frequency that is odd or even a multiple of its input frequency. For example, for a signal with a frequency of 100,000 cycles per second (CPS) or 100 kilohertz (KHz), the frequency multiplier can produce a signal of 200 or 300 kHz. The frequency multiplier is commonly used in communication circuits for the production of the required signal frequency due to the reference frequency.
The main mechanism for the frequency multiplier is called non -linear signal transmission. When the frequency generator output is displayed on the spectrum analyzer, there is a single vertical line with the upper end aligned with the signal amplitude. The level can be 1 volt (v). The horizontal axis indicates the frequency of this signal. For example, the frequency of 500 million Hertz (Hz) or 500 Megahertz (MHz) will be shown on the horizontal axis of the spectrum analyzer.
When the reference frequency is supplied to a non -linear device amplifier C -class C or detector is the resultFrequency spectrum with harmonious or multiples of the original frequency. Using the band filter with the ability to pass only the desired outputs, the result is the desired harmonious. In the above example 500 MHz, the second harmonic at 1,000 MHz can be derived.
The frequency multiplier access is used in special cases where only one output frequency is required, due to different combinations of band filters needed to create pure sinusoid signals. For example, a signal of 10 billion cycles per second or 10 Gigahertz (GHz) may not be possible to generate directly. It may be possible to use an 5 GHz oscillator or a frequency generator followed by a multiplier and a band filter tuned to 10 GHz.
Also known as a blender, the signal multiplier is used in frequency modulation systems (FM) to create a FMTO carrier is moved to the required transfer rate. Blender, on the divideThe frequency multiplier requires two inputs. Although it is designed as an analog multiplier, the mixer output actually generates the sum and differences of input signals.
4 Varactor with one diode uses one capacity diode that changes with the level of reverse distortion on the diode. Capacitance culminates when the tension is zero, while the capacity decreases in a positive or negative voltage fluctuations via HBV. This characteristic makes HBV useful for frequency multiplication.
