A frequency multiplier is an electrical circuit used in electronics that produces an output signal with an output frequency that is a harmonic (multiple) of the input frequency.
A nonlinear circuit makes up frequency multipliers, which distort input signals and produce harmonics as a result. The required harmonic frequency is then chosen via a bandpass filter, which also filters out the undesirable fundamental and other harmonic frequencies from the output.
In frequency synthesisers and communication circuits, frequency multipliers are frequently used.
It may be more cost-effective to create a signal at a lower frequency using low-cost, low-power equipment, and to utilise a frequency multiplier chain to increase the output frequency to a microwave or millimetre wave range.
The Global frequency multiplier market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
