Description
Technical field
The utility model relates to passive device industry and antenna industry, relates in particular to a kind of microstrip power divider.
Background technology
Domestic present power splitter mainly is divided into two types of microstrip power divider and cavity power splitters.The cavity power splitter mainly is used for indoor covering system separately, and microstrip power divider is because power is less uses scarcely separately, but in multiunit aerial array, generally uses that microstrip power divider is realized the multiple unit oscillator and close.In order to realize the wide frequency antenna coupling of 800-2500MHz, often use two microstrip power dividers, realize low frequency coupling, a realization high frequency coupling for one; Perhaps use complicated gloomy microstrip power divider of Hall gold that contains isolation resistance to realize 800-2500MHz wideband coupling, the former uses two power splitters, and latter's structure also needs isolation resistance than complicacy, and these are all given and produce the debugging deleterious impact.
The utility model content
1, technical problem to be solved:
Realize the microstrip power divider that the broad-band antenna coupling is used in the prior art, be with two microstrip power dividers or the complicated gloomy microstrip power divider of Hall gold that contains isolation resistance of utilization structure.
2, technical scheme:
To above problem, the utility model provides a kind of wideband microstrip power divider, comprises power splitter input 1; Power splitter main body 2, power splitter output 3, wiring board 4; Power splitter shell (5), power splitter main body 2 is a microstripline, power splitter main body 2 is arranged on the wiring board 4; Be provided with power splitter input 1 and power splitter output 3 in the power splitter main body 2; Power splitter shell 5 surrounds other five and is connected with wiring board 4 except that wiring board 4 is positive, and it is characterized in that: power splitter main body 2 is that the impedance conversion of level Four wiring board is excessive, than the circuit bending of length the level Four impedance excessively can be arranged in the wiring board 4 level Four simultaneously.
Input port uses 50 ohm microstrip circuits of standard, and number of output ports is used 50/N (N is aerial array quantity) according to aerial array quantity.

3, beneficial effect:
The wideband microstrip power divider that the utility model provides not only can be realized the ultra wideband good fit of 800-2700MHz of multiple antenna, and structure is dexterous, and cost is low, and the production debugging difficulty also reduces greatly.
Description of drawings
The structural representation of Fig. 1 the utility model.
Embodiment
Come the utility model is further specified below in conjunction with accompanying drawing and instance, like Fig. 1, a kind of wideband microstrip power divider; Comprise power splitter input 1, power splitter main body 2, power splitter output 3; Wiring board 4, power splitter shell 5, power splitter main body 2 is a microstripline; Power splitter main body 2 is arranged on the wiring board 4, is provided with power splitter input 1 and power splitter output 3 in the power splitter main body 2, and power splitter shell 5 surrounds other five and also is connected with wiring board 4 except that wiring board 4 fronts; It is characterized in that: power splitter main body 2 is excessive for the impedance conversion of level Four wiring board, and simultaneously that level Four is long circuit bending excessively can be arranged in the wiring board 4 the level Four impedance.
Power splitter is generally level Four impedance conversion transition, and this microstrip antenna also is that the level Four impedance conversion is excessive, and excessively from the first order to the fourth stage, length is longer relatively in the level Four impedance; In practice, because length is longer, the length of power splitter will be grown naturally, makes the volume of power splitter bigger; When applying in the middle of the antenna, natural volume is bigger, the utility model with each level of level Four impedance excessively utilization microstrip antenna right angle bending principle carry out bending; Performance is unaffected, but length shortens compact conformation; As shown in Figure 1, enable to be arranged in the wiring board 4, thereby be fit to be positioned over multiple antenna inside.
The antenna main feeder is connected to power splitter input 1, and signal is transferred to power splitter output 3 through power splitter main body 2 and is transferred to each unit oscillator of antenna to the signal of constant amplitude, homophase again.
Input port uses 50 ohm microstrip circuits of standard, and number of output ports is used 50/N (N is aerial array quantity) according to number of output ports according to aerial array quantity.For example, antenna oscillator has 4 oscillators, N=3, and time device input port uses 50 ohm microstrip circuits, and output port uses 50/4=12.5 ohm microstrip circuit to realize that one is divided into 4 impedance conversion.Simultaneously for can with being connected of each antenna oscillator, at the output setting brace 6 identical with the antenna oscillator number, brace 6 is evenly distributed on the output 3 and is one with output 3, and is as shown in Figure 1.
Because the multiple antenna oscillator is with width of cloth homophase, each oscillator signal the voltage amplitude difference seldom occurs and harasses at the power splitter output port, can not realize isolation effect so the microstrip power divider of the utility model does not need isolation resistance.
Wiring board 4 is a double face copper, and power splitter main body 2 is arranged on wiring board 4 fronts through corrosion wiring board technology, and for better effect, wiring board 4 is for being high-performance poly tetrafluoroethene glass-cloth board wiring board.
The conventional method that is connected of power splitter housing 5 and wiring board 4 is to use rivet or screw power splitter housing and wiring board reverse side to cover copper face, and this sampling point contact can not guarantee good ground connection performance, and the utility model is to this deficiency; Adopted power splitter housing 5 reverse side to fan the air; Pour into wiring board 4 reverse side to tin and cover copper face and weld, through facts have proved the method for tin filling, it is one that the face contact can be covered the copper face weldering to power splitter housing and wiring board; Abundant ground connection, function admirable.Power splitter housing 5 reverse side are made a call at 6 and are fanned the air, 6 o'clock minutees parallel two rows, and every row evenly distributes.
