Description
Technical field
The present invention relates to a kind of RF-MW Photonics broadband reception module.
Background technology
Microwave communication is the important communication mode of modern communicationses, and microwave communication has communication band wide, can achieve wireless biography
Defeated.Modern microwave communication adopts wireless transmission method mostly.But, it is wirelessly transferred space opening and is easily disturbed.Microwave communication is also
It is exactly wire transmission to have, and microwave wire transmission loss is big, and coaxial cable high cost, weight are big.
Content of the invention
It is an object of the invention to provide a kind of RF-MW Photonics broadband reception module, is being transmitted across with solving existing microwave communication
It is vulnerable to interference in journey, loss is big, the problem of high cost.
For solving above-mentioned technical problem, the present invention provides a kind of RF-MW Photonics broadband reception module, including photodiode
D, DC channel, sample circuit and variable-frequency filtering circuit.The negative electrode of photodiode D is connected with DC channel；Photodiode D
Anode be connected with sample circuit and variable-frequency filtering circuit respectively.Wherein, sample circuit is a sampling resistor R；DC channel bag
Include the filter capacitor C and taper inductance L with DC channel；Variable-frequency filtering circuit includes amplifier A, the frequency mixer M being sequentially connected
With wave filter L；Amplifier A is connected with the anode of photodiode D.
Beneficial effects of the present invention are：Light pricker remote technology is present invention employs, light pricker transmits modulated optical signal, carried out remote
After Distance Transmission, then using this RF-MW Photonics broadband reception module by modulate optical signal demodulation be microwave telecommunication number, then
Microwave telecommunication number is amplified, frequency conversion, Filtering Processing, finally obtain information needed.Invention enhances microwave transmission process
In capacity of resisting disturbance, reduce loss, and greatly reduce the cost of microwave transmission.
Description of the drawings
Structural representations of the Fig. 1 for one embodiment of the invention.
Specific embodiment
Below the specific embodiment of the present invention is described, and this is understood in order to those skilled in the art
Bright, it should be apparent that the invention is not restricted to the scope of specific embodiment, for those skilled in the art,
As long as in appended claim restriction and the spirit and scope of the present invention for determining, these changes are aobvious and easy to various change
See, all utilize the innovation and creation of present inventive concept in the row of protection.
Glistening light of waves electricity broadband reception module as shown in Figure 1, including photodiode D, DC channel, sample circuit and frequency conversion
Filter circuit.The negative electrode of photodiode D is connected with DC channel；The anode of photodiode D respectively with sample circuit and change
Frequency filter circuit connects.
DC channel includes the filter capacitor C with DC channel and taper inductance L.Wherein, taper inductance L effects are to prevent
Microwave signal to ground, equivalent to a high frequency choke coil.
Above-mentioned sample circuit is a sampling resistor R, and which has not only acted as the effect of a resistance sampling, has also corresponded to radio frequency
Build-out resistor.Because photoelectric chip output is generally high resistant too, and the Microwave Net of our routines is with 50 ohm as transmission resistance
Anti-, so, photoelectric chip output needs an impedance matching to before radio frequency amplifier A.
Variable-frequency filtering circuit includes amplifier A, frequency mixer M and the wave filter L being sequentially connected, amplifier A and two pole of photoelectricity
The anode connection of pipe D.Microwave signal RF after demodulated, after amplifier A amplifies, is mixed with local oscillator L0 through frequency mixer M
Frequently, then intermediate-freuqncy signal IF is finally wanted through low pass filter L outputs.
