The utility model adopts a series resistance ring and a parallel resistance sheet to reduce the Q value of the packaged diode and weaken the resonance effect of the packaged parameter of the packaged diode and simultaneously adopts a regulating mechanism to regulate the upper and the lower positions of the diode in waveguides, and the diode is locked by a locking nut after regulated, so the voltage-sensitivity frequency response of the detector is improved. Compared with the previous wide-band detector made of a pipe core, the utility model has the characteristics of high reliability, easy assembly and regulation, replacement of the diode, low cost, etc., the voltage standing wave ratio is not larger than 1.5 in the integral wave-guide frequency band, and therefore, the utility model is especially suitable for using as a power detector in a six-port network analyzer.
Description
The utility model is the wave detector that is used for millimetre-wave circuit.
Millimetre-wave detector is widely used in the millimeter wave measurement system.The product R422A(that existing a kind of Ka wave band broadband detector is a U.S. Hewlett-Packard Corporation sees Hewlett-Packard Corporation's product catalogue in 1984), its leading indicator is: voltage sensitivity 〉=0.3mV/ μ W, the sensitivity frequency response≤± 2dB voltage standing wave ratio (VSWR)＜3.It makes with diode chip, and reliability is not too high, makes relatively difficulty, and the cost height can't be changed diode, and its voltage standing wave ratio (VSWR) is up to 3, and this is in many occasions, and particularly in the six-port network analyser, application is restricted.In the past, people generally believed, in millimere-wave band, were difficult to make broadband detector with the encapsulation diode.
The utility model is attempted to adopt the encapsulation type diode to constitute the millimeter wave broadband wave detector by new construction, to improve reliability, reduces voltage standing wave ratio (VSWR), reduces cost.
The utility model adopts the waveguide type structure, adopt a low barrier Schottky diode (12) of encapsulation type and a cover installing component (16), comprising ring flange (1), main waveguide (2), coaxial outer conductor (3), coaxial inner conductor (5), gradual change shape ridge (11), plug (15) and insulation spacer (8) etc.Coaxial outer conductor (3) and coaxial inner conductor (5) etc. constitute the output of wave detector.Gradual change shape ridge (11) is used to make the characteristic impedance of diode (12) impedance and main waveguide (2) to mate as far as possible.Insulation spacer (8) is used for stopping direct current, constitutes filter capacitor simultaneously, to prevent radio-frequency leakage.This wave detector also uses a series electrical balk ring (9) and two parallel resistance sheets (10).Series electrical balk ring (9) is enclosed within on the electrode of diode (12), and parallel resistance sheet (10) inserts in the both sides of ridge (11), and they are used to reduce the Q value of diode, weakens the resonance effect of its encapsulation parameter, increases the bandwidth of operation of wave detector.Have in this wave detector to go up and press nut (4) and following screw (13), make that the upper-lower position of diode (12) in waveguide is adjustable, can improve the voltage sensitivity frequency response of wave detector like this, adjust the available set nut in back that finishes and pin.
The utility model is compared with the broadband detector that makes with tube core in the past, has the reliability height, debug characteristics such as easy, that diode is replaceable, cost is low, and voltage standing wave ratio (VSWR) is not more than 1.5 in the whole wave guide frequency band.Therefore, it is particularly suitable for doing the power detector in the six-port network analyser.
An embodiment of the present utility model is seen accompanying drawing.Among the figure: 1. ring flange; 2. main waveguide; 3. coaxial outer conductor; 4. go up and press nut, make with insulating material; 5. coaxial inner conductor is drawn the output voltage of wave detector by it; 6. press mother, make with insulating material; 7. the inner wire collar, it is by pressing female (6) to compress; 8. insulation spacer; 9. series electrical balk ring, 10. parallel resistance sheet; 11. gradual change shape ridge, parallel resistance sheet (10) inserts in the both sides of ridge; 12. the encapsulation type Schottky hangs down barrier diode, 13. times screws; 14. locknut; 15. plug.This wave detector in Ka wave band whole frequency band (26.5～40GHz) reach: voltage sensitivity 〉=0.3mV/ μ W, the sensitivity frequency response＜± 2dB, voltage standing wave ratio (VSWR)≤1.5.
