Description
The invention belongs to a kind of microwave device that is used for the microwave phase shift.
The device that is used for the microwave phase shift that has retrieved is a United States Patent (USP), and name is called " broadband microwave analog phase shifter ", and application number is 738794, and the applying date is on May 28th, 1985, and notification number is 4638269, and the day for announcing is on June 20th, 1987.This phase shifter adopts the version of 3dB hybrid coupler and reactance type reflection termination, and coupler and each element of reflection termination are integrated on the crystalline material sheet.The technology more approaching with the present invention also has, adopt the version of the reflection termination of circulator and a pair of variable capacitance diode formation, its process also is to adopt integrated or the mixing integrated technology, circulator and variable capacitance diode by a whole set of complicated semiconductor processes such as photoetching, diffusions, are integrated on the block semiconductor chip.All these prior arts owing to adopt integrated or the mixing integrated technology, are subjected to the restriction of device size, can only be operated in the above wave band of X, can not make more broadband phase shifter; In order to obtain linear phase-shift characterisitc and to insert loss uniformly, in design, be cost usually to reduce phase shift range, be difficult to make 360 ° of linear phase shifters, and also integrated circuit fabrication process, complex process, rate of finished products is low, involves great expense.
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, design a kind of non-integratedly or mix integrated analog phase shifter, can be operated in below the X-band, simplify technology and realize that 360 ° of phase shifts are continuous adjustable, and the phase shift size is linear with bias voltage.
Analog 360 ° of reflection type linear phase shifters of the present invention are made of circulator and reflection termination box.Circulator and reflection termination box right and wrong on mechanical structure are integrated or mix integrated self-existent separately form, and the two connects by coaxial fitting.Said circulator is a microwave three terminal device, the microwave transmission network that Ferrite Material is made is housed in its shell, three ends of corresponding three terminal device are connected to microwave input plug seat, microwave output plug seat and plug-in type socket respectively on its shell, this plug-in type socket connects by coaxial fitting heel-tap reflex terminal box, constitutes the microwave transmission path.The bias voltage connector assembly is housed on the box of reflection termination, the reflection termination circuit is housed in it.The reflection termination circuit that is equipped with in the box of said reflection termination is the reflection termination printed circuit board (PCB) of making of the composite microwave medium substrate, is etched into the distributed circuit of direct current symmetrical expression bias structure on it and uses the microstrip type variable capacitance diode.The distributed circuit of said direct current symmetrical expression bias structure mainly is made up of two partially installing capacitors, bias inductors and high resistant microstrip line, two partially installing capacitors are connected by the resistance microstrip line, bias inductors one end is used for input offset voltage, and the other end just in time is connected to high resistant microstrip line mid point.Bias voltage is added on high resistant microstrip line mid point by the bias inductors in the circuit of reflection termination, because phase-shift phase has linear relationship with deviator voltage, and by reconciling the bias voltage size size of phase-shift phase is regulated.
Because the distributed circuit form that the reflection termination adopts this composite microwave medium substrate to make is operated in below the X-band phase shifter effectively.
The concrete form of the self-existent mechanical structure form of circulator in aforementioned and reflection termination box, distributed circuit, reflection termination printed circuit board (PCB) is respectively referring to Fig. 1～3.
Fig. 1 is a kind of contour structures schematic diagram of the present invention.
Fig. 2 is a distributed circuit of the present invention.
Fig. 3 is a kind of reflection termination of the present invention printed circuit board (PCB) schematic diagram.
Among Fig. 1, the 10th, circulator, the 11st, the reflection termination box, the two is connected by coaxial fitting 12.Said coaxial fitting 12 can be pin, hole plug-in type socket, pegs graft respectively behind circulator 10 and the reflection termination box 11 in two ends, with external helicoid locking, guarantees that two coupled parts have to electrically connect reliably and mechanical attachment.The control voltage of controlled microwave phase shift is input to distributed circuit in the reflection termination box 11 by the bias voltage connector assembly 15 on the reflection termination box 11.Microwave signal is by 13 inputs of microwave input plug seat, behind circulator 10 and coaxial fitting 12, the distributed circuit phase shift in the terminal box 11 that is reflected is again through coaxial fitting 12 and circulator 10, by 14 outputs of microwave output plug seat, and moving relative to the microwave signal generation phase place of importing.
Because circulator 10 and reflection termination are not integrated or mix integrated structure, thereby can be made into the following phase shifter of X-band.During general assembly in reflection termination box 11 the filling microwave absorbing material, can improve the uniformity of amplitude fluctuation.
In order to connect the reflection termination box 11 of different-waveband neatly, coaxial fitting 12 can be with coaxial L16J-K connector assembly, this coaxial plug seat plays the signal of Transmission Microwave signal in the middle of circulator 10 and reflection termination circuit, concrete structure is pin, the hole plug-in type connector assembly of 16, peg graft by the vent needle of pin hole and circulator 10 and reflection termination box 11 respectively in two ends, with external helicoid locking, circulator 10 and reflection termination box 11 are combined as a whole constitute the microwave signal transmission channel again.Select for use the anti-terminal box 11 of a plurality of different-wavebands to connect same circulator 10 by coaxial L16J-K connector assembly respectively, thereby obtain the phase shifts of a plurality of wave bands, play the effect that obtains the broadband phase shifts.Come for microwave input plug seat 13, microwave output plug seat 14 are distinguished with bias voltage connector assembly 15, occur wrong plug when being unlikely to use, the bias voltage connector assembly 15 of voltage controling end can be selected coaxial L8K formula connector assembly for use.
