Description
Technical field
The present invention relates to power divider field, especially a kind of unequal power distributor of wide isolation strip.
Background technique
Power divider is a kind of multiport microwave device, is not divided into the power equal part of signal all the way or multichannel letter
Number, in the equipment such as application and wireless communication, radar of including board.Wilkinson power divider is a kind of relatively common broadband power
Distributor can facilitate realization using non-band structure on planar circuit, the occasion not high suitable for bandwidth requirement.
In microwave system, insertion loss that unexpectedly may be small can be all required as far as possible, to reduce the energy loss of system, and
It is required that the amplitude and phase of each branch are consistent, to guarantee the efficient distribution and superposition of signal.Currently, with communication equipment
Development, the requirement for frequency band is also more and more wider, so the broadband character of power divider also becomes more and more important.However, traditional
The broadband of power divider be limited to this index of the isolation of low side of frequency band, solution is exactly to pass through increase series,
But since the increase of series has, and bring insertion loss.
Summary of the invention
Present invention mainly solves the problem of be to provide the unequal power distributor of wide isolation strip a kind of, Weir can be reduced
The series of the gloomy power divider of gold, while reaching higher frequency band.
To solve the above problems, one technical scheme adopted by the invention is that: a kind of power point of broadband not equal part is provided
Orchestration, including Wilkinson power divider, the Wilkinson power divider are connected by microstrip line, the Wilkinson
Power divider includes isolation resistance, and the isolation resistance both ends are connected to the microstrip line, the microstrip line and isolation
Resistance is integrated on 6010 plate of Rogers, the microstrip line include sequentially connected input transmission line, matched transmission line, every
From transmission line, output transmission line, the matched transmission line connection isolation transmission line, the isolation transmission line connects isolation resistance,
The isolation resistance ground connection.
It is in contrast to the prior art, the beneficial effects of the present invention are: by selection 6010 plate of Rogers, and
Connection isolation transmission and isolation resistance among two section matched transmission lines, to can be reduced the grade of Wilkinson power divider
Number, while reaching wider frequency band and wider isolation strip, have many advantages, such as that structure is simple, it is easy to make.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of wideband power distributor of the embodiment of the present invention.
Fig. 2 is the structural schematic diagram of the microstrip line of wideband power distributor of the embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, carries out to technical solution in the embodiment of the present invention clear, complete
Ground description.In the present specification, term " connection " indicates to be electrically connected between two elements, even if other elements are between,
But as long as forming electronics movable passageway between element, then it can be considered connection.
It is the structural schematic diagram of wideband power distributor of the embodiment of the present invention referring to Fig. 1.At this point, power divider 100 can
Including an input transmission line 101, two output transmission lines 102,103, four matched transmission lines 104,105,106,107, four
A isolation transmission line 108,109,110,111, two isolation resistances 112,113.The present embodiment is work in 5GHz, in 3.8GHz
The exemplary circuit for improving broadband character to 6.6GHz and designing.
At this point, input transmission line 101 and output transmission line 102,103 characteristic impedances can 50 Ω of value.Output is transferred to pass
The output power of defeated line 103 is twice for being transferred to output transmission line 102.Matched transmission line 104,105 is connected to input transmission
Between line 101 and output transmission line 102.104 characteristic impedance of matched transmission line is 50 Ω, electrical length 270°.Matched transmission line
105 characteristic impedances are 90, electrical length 170°.Matched transmission line 106,107 is connected to input transmission line 101 and output transmission line
Between 103.106 characteristic impedance of matched transmission line is 100 Ω, electrical length 270°.107 characteristic impedance of matched transmission line is 80,
Electrical length is 170°.Isolation transmission line 108 is connected between matched transmission line 104 and matched transmission line 105, characteristic impedance 50
Ω, electrical length 90°.Isolation transmission line 108 is sequentially connected isolation transmission line 109,110,111.The spy of transmission line 109 is isolated
Sign impedance is 30 Ω, electrical length 100°.The characteristic impedance that transmission line 110 is isolated is 30 Ω, electrical length 70°.Transmission line is isolated
111 characteristic impedance is 50 Ω, electrical length 90°.Isolation electricity is connected between isolation transmission line 108 and isolation transmission line 109
Resistance 112, resistance value are 66 Ω.It is connected to isolation resistance 113 between isolation transmission line 110 and isolation transmission line 111, resistance value is
33Ω.Isolation resistance 112,113 is grounded.
Fig. 2 is according to the insertion loss of the broadband of the present invention not power divider of equal part the one of isolation and reflection coefficient
Example diagram solution.As shown in Fig. 2, broadband unequal power distributor in 3.8GHz to 6.6GHz insertion loss 201 close to-
2dB, insertion loss 202 show that two output transmission line power ratios are 2 close to -5dB, realize that equal part broadband power does not distribute.Together
When in the isolation of 3.9GHz to 6.3GHz be lower than -15dB, realize wide isolation.
