Mini-Circuits' frequency doublers offer a new degree of freedom in designing frequency multiplier chains. Their multi-octave band width and excellent rejection of fundamental and third harmonics enable a significant reduction in filter requirements.

Dec 15, 2003 · Using a doubler instead of a second clock oscillator prevents the beat frequencies that might otherwise occur. This design idea appeared in the December 15, 2003 issue of EE Times magazine.

Frequency multipliers will always be a way of generating the highest frequencies. • A frequency multiplier has the property that the frequency of the output signal has an integer multiple of the input frequency. This approach is commonly adopted in microwave transceivers.

Multipliers are nonlinear, two-port devices where an input signal is used to create an output signal that is at a higher harmonic. The most common multipllier is a doubler. The idea is that you take a periodic signal (ideally a single tone) and distort it. If you look at the Fourier series, you will find various components at n x F0.

Frequency doublers are commonly constructed from full-wave voltage rectifiers and have high conversion efficiency with good odd harmonic rejection. The higher even harmonics rapidly drop by the square of the harmonic number.

Driving the mixer with two signals in quadrature eliminates a DC term and significantly reduces the fundamental frequency output and the undesired harmonics. K6IQL used a power splitter to with one leg driving a 5 MHz phase shift network to generate the quadrature signals.

If you are working at frequencies of the order of 850MHz to 4GHz and find that a frequency multiplier is required, the HMC 187, HMC 188 and HMC 189 (see table) frequency doubler may be just the solution you are looking for.

Sep 8, 1999 · Mini-Circuits' frequency doublers are economically priced while covering the very broad frequency range from 5 KHz to 3000 MHz. They offer a very low conversion loss, from 11 dB, and high spurious rejection 40 dB. These doublers give exceptional unit-to …

A Frequency Doubler is device that outputs the same signal that is fed into it but with double the frequency. So it gives out exactly twice (2x) the frequency as output. So, for example, if a frequency doubler has a 500Hz signal as its input, it will output a 1KHz signal.
