Abstract

PURPOSE:To obtain a compact 180 deg. electric power distributor which is easily produced by making use of the conversion between a strip line and a slot line to divide a signal into two parts and securing a 180 deg. phase difference between both signals. CONSTITUTION:The signal supplied through an input terminal 5 is transmitted through the 1st strip line 1 and divided by a converter 8 into both directions along a slot line 4 with connection of 3dB respectively. These divided signals are connected to the 2nd and 3rd strip lines 2 and 3 at converting parts 9 and 10 through the line 4 and then delivered from the 1st and 2nd output terminals 6 and 7 through each strip line. As a result, the 1/2 signal supplied through the terminal 5 is delivered to both terminal 6 and 7 respectively as long as the loss produced in mid course is neglected. Furthermore the connecting directions are set opposite to each other between the line 4 and the lines 2 and 3 when the conversion is performed between them at the parts 9 and 10. Thus the phase difference can be set at 180 deg. between both signals delivered through terminals 6 and 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power divider, and more particularly to a 180't power divider in which two distributed waves have an antiphase relationship.

[Conventional technology]

Conventionally, an input signal is divided into two to create two output signals.
The phase difference between the two divided signals is 180', and the specific power divider uses a directional coupler using a distributed constant circuit and a pseudo delay circuit.

FIG. 2 is a block diagram of a conventional 1800 power divider. In the figure, 11 is an input terminal, 12 is a first output terminal, 1
3 is the second output terminal, 14 is a 3dB directional coupler, 15
16 represents a coupling terminal, 16 represents a pass terminal, and 17 represents a pseudo delay circuit.

The signal input from the input terminal 11 is connected to the coupling terminal 15 by a 3 dB directional coupler 14 configured by a planar circuit.
1/2 of the input signal power is distributed to the pass terminal 16 and the pass terminal 16, respectively. Since the signal at the pass terminal 16 is delayed in phase by 90' from the coupling terminal 15, by further connecting 14 delay lines 17 of the signal wavelength to the pass terminal side, the first output 12 and the second output The phase difference in the holder 13 can be 180'.

[Problem that the invention seeks to solve]

The conventional 180° power divider as described above has a 3 dB directional coupler configured by distributed constants, so the planar circuit pattern becomes extremely fine and difficult to manufacture, and it also includes a λ4 delay circuit. Therefore, the disadvantage is that the entire circuit becomes larger.

[Means for solving problems]

To solve the above problems, the 1800 power divider of the present invention is configured to include three strip lines and a slot line that intersects each of the strip lines at a conversion section.

In the first converting section, the signal from the first strip line is divided and coupled to the slot line in the direction of both ends thereof, and in the second and third converting sections, the signal from the slot line is coupled to the second and third strip lines. It is characterized by being coupled to the strip lines in such a way that they are in an antiphase relationship with each other.

In this way, two divided signals having an opposite phase relationship are obtained.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a circuit diagram of an embodiment of a power divider according to the present invention. In the figure, l is the first stripline,
2 is the second stripline, 3 is the third stripline, 4 is the slotline, 5 is the input terminal, 6 is the first output terminal, 7 is the second output terminal, 8 is the stripline-slotline conversion 9 is a slotline-stripline converter, and lO is a slotline-stripline converter.

The signal input from the input connector 5 passes through the first stripline 1, is coupled to the slotline 4 by 3 dB in both directions, and is split in the converter 8. , and output from the first and second output terminals 6.7 through the respective strip lines.

As a result, if losses along the way are ignored, 1/2 of the signal input from the input terminal 5 will be output to each of the output terminals 6 and 7.

9. When converting the slot line 4 and the second and third strip lines 2.3 in the conversion section 9, 104c, the direction of the connection is reversed as shown in the figure. , the phase difference between the signals output at the output terminals 6 and 7 can be set to 1800 degrees.

〔Effect of the invention〕

As explained above, the present invention utilizes conversion between a strip line and a slot line to divide the signal t-2 so that each signal has a phase difference of 180'.
Since no dB directional coupler or λ4 delay circuit is used, it is possible to obtain an 1800' it power divider which is small and easy to manufacture.
