The signal modulation frequency multiplier has a simple integrated design structure and can select different band-pass filtering units, so as to finish frequency multiplication requirements of different frequency ranges and frequency multiplication times; the signal modulation frequency multiplier has good commonality; and meanwhile, the control part is arranged, so that the signal modulation frequency multiplier can detect a pulse signal generated by each part and an output signal is controlled. The signal modulation frequency multiplier has higher stability is convenient to adjust.
Description
Technical field
The present invention relates to a kind of signal modulator multiplier.
Background technology
In fields such as radar, communications, its equipment often needs the external frequency source that operating frequency is higher, and strict to the stability requirement of frequency.General LC oscillator can't meet the demands.If adopt lower but the crystal oscillator that stability is high of frequency to produce high order harmonic component, pass through processing such as filtering, amplification again, then can obtain comparatively stable high-frequency oscillation signal through nonlinear circuit.
Existing frequency multiplier complex structure can not satisfy the frequency multiplication requirement of each frequency range, function singleness, and high-frequency oscillation signal is unstable.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of simple in structure, highly versatile, signal modulator multiplier that stability is high, easy to adjust.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of signal modulator multiplier is provided; Comprise the amplifier unit, diode and the filter unit that connect successively; Said amplifier unit one end is connected with control-signals generator, and said amplifier unit, diode, filter unit and control-signals generator are connected with control assembly respectively.
In preferred embodiment of the present invention, said amplifier unit is an amplifier.
In preferred embodiment of the present invention, said filter unit is the bandpass filtering unit.
In preferred embodiment of the present invention, be in series with second amplifier and second filter unit behind the said filter unit successively.
In preferred embodiment of the present invention, said control assembly is a level.
The invention has the beneficial effects as follows: signal modulator multiplier of the present invention global design is simple in structure, can select different bandpass filtering unit, accomplishes the frequency multiplication requirement of different frequency range and frequency multiplication number of times; Versatility is good, simultaneously, owing to be provided with control assembly; Can detect the pulse signal that each position produces; And control output signal, stability is higher, easy to adjust.
Description of drawings
Fig. 1 is the structural representation of signal modulator multiplier one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, amplifier unit, 2, diode, 3, filter unit, 4, control-signals generator, 5, control assembly.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of signal modulator multiplier; Comprise the amplifier unit 1, diode 2 and the filter unit 3 that connect successively; Said amplifier unit 1 one ends are connected with control-signals generator 4, and said amplifier unit 1, diode 2, filter unit 3 are connected with control assembly 5 respectively with control-signals generator 4.
Said amplifier unit 1 is an amplifier, and said filter unit 3 is the bandpass filtering unit, and said control assembly 5 is a level.
Suppress limited in one's ability because the band of single filter unit is outer, the power of clutter frequency component after the filtering, still bigger, therefore behind filter unit 3, be in series with second amplifier and second filter unit successively, promptly can obtain comparatively pure frequency-doubled signal.
Produce control signal through control-signals generator 4 and send to amplifier, amplifier amplifies signal through diode 2, because the nonlinear characteristic of diode 2; Produced the high order harmonic component of a plurality of input signals,, can take out harmonic component through 3 filtering of bandpass filtering unit; Simultaneously; Control assembly 4 detects the pulse signal that each parts produces, and the control output signal frequency makes stable output signal property higher.
Compared with prior art, signal modulator multiplier of the present invention global design is simple in structure, can select different bandpass filtering unit; Accomplish the frequency multiplication requirement of different frequency range and frequency multiplication number of times, versatility is good, simultaneously; Owing to be provided with control assembly 5, can detect the pulse signal that each position produces, and control output signal; Stability is higher, easy to adjust.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
