Abstract
The invention discloses a high-accuracy and low-loss loaded line microwave phase shifter. A microstrip line adopts a long cylindrical structure, an input port and an output port are formed in two ends of the microstrip line, a PIN diode is connected to each of one-third position and two-third position of the microstrip line, the other ends of the PIN diodes are further connected with ground capacitors, and the input port and the output port in two ends of the microstrip line adopt protruding design and are more conveniently connected in an electric circuit. Compared with the prior art, the high-accuracy and low-loss loaded line microwave phase shifter has enough phase shifting accuracy, is high in phase shifting stability and doesn't change with temperatures, signal level and the like; the insertion loss is low, the port standing waves are small, the bearing power is high, the phase shifting speed is high, and required control power is small.
Description
Technical field
The present invention relates to the phase shifter, specifically refer to a kind of low-loss loaded line microwave phase shifter of high accuracy.
Background technology
Microwave phase shifter is phased-array radar, satellite communication, the core component in mobile communication equipment, its work frequency
Band, insertion loss directly affect capacity of resisting disturbance and the sensitivity of these equipment, and the weight of system, volume and cost,
Therefore research broadband, the phase shifter of filter with low insertion loss militarily have great importance with Civil Satellite Communication field.To electric controlled sliding
The requirement of phase device is: has enough phase shifting accuracies, stability of phase shift is high, does not change with temperature, signal level etc.；Insertion loss
Little, port standing wave is little, bears power height, and phase shift speed is fast, and required control power is little.
Content of the invention
The technical problem to be solved is to provide a kind of high accuracy low-loss loaded line microwave phase shifter.
For solving above-mentioned technical problem, a kind of low-loss loaded line microwave phase shifter of high accuracy of the present invention, including micro-strip
Line, input port, output port, pin pipe, ground capacity, described microstrip line is oval rod structure, is respectively arranged at two ends with input
Mouth and output port, respectively connect a pin pipe at microstrip line 1/3rd and at 2/3rds, the pin pipe other end is also connected with one
Individual ground capacity.
Pin pipe has different forward and reverse characteristics, can be equivalent to small capacitances when it is reverse biased and approximately open a way, and
Then variable resistance can be equivalent in forward bias, if bias increases, its resistance then reduces.
When pin pipe is positively biased, high resistance can be equivalent to and approximately open a way, signal inputs from input port first, from a
Phase shift to b is θ1；And pin is when managing as reverse bias, small capacitances can be equivalent to, phase shift from a to b for the signal is changed into θ2, both differences
It is exactly the phase shift of phase shifter, last signal exports from output port.This loaded line phase shifter can only produce less phase shift；Relatively
Big phase shift then must adopt the other structures such as hybrid juction phase shifter just to enable.
The input port at the two ends of microstrip line and output port design for protruding-type, convenient company in electric wiring
Connect.
Compared with prior art, the present invention has enough phase shifting accuracies, and stability of phase shift is high, not with temperature, signal level
Deng change；Insertion loss is little, and port standing wave is little, bears power height, and phase shift speed is fast, and required control power is little.
Brief description
Fig. 1 is a kind of schematic diagram of the low-loss loaded line microwave phase shifter of high accuracy of the present invention.
In figure, 1- microstrip line, 2- input port, 3- output port, 4-pin manages, 5- ground capacity.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of low-loss loaded line microwave phase shifter of high accuracy, including microstrip line 1, input port 2, defeated
Exit port 3, pin pipe 4, ground capacity 5, described microstrip line 1 is oval rod structure, is respectively arranged at two ends with input port 2 and output
Port 3, respectively connects a pin pipe 4 at microstrip line 1/1st three and at 2/3rds, the pin pipe other end is also connected with a ground connection
Electric capacity 5；The input port 2 at the two ends of microstrip line 1 and output port 3 design for protruding-type, convenient company in electric wiring
Connect.
Pin pipe 4 has different forward and reverse characteristics, can be equivalent to small capacitances when it is reverse biased and approximately open a way,
And variable resistance then can be equivalent in forward bias, if bias increases, its resistance then reduces.
When pin pipe 4 is positively biased, high resistance can be equivalent to and approximately open a way, signal inputs from input port 2 first,
Phase shift from a to b is θ1；And pin pipe 4 be reverse bias when, small capacitances can be equivalent to, phase shift from a to b for the signal is changed into θ2, both
Difference be exactly the phase shifter phase shift, last signal exports from output port 3.This loaded line phase shifter can only produce less phase
Move；Larger phase shift then must adopt the other structures such as hybrid juction phase shifter just to enable.If the positive bias phase shift the phase shifter
Be considered as zero, and reverse bias phase shifted design become π, then the phase shifter just become 0～π phase converter.If replacing pin pipe 4 with varactor simultaneously
Adjust bias value, then constitute the automatically controlled variable phase shifter of phase-shift phase continually varying.
Because the control object of automatically controlled device is different, required index is also different.Except operating frequency, bandwidth
Outside the general requirements such as standing wave ratio of input voltage, also should there is the special index such as switch time, switch power.
