Abstract

The invention relates to power distribution devices between transmission lines. The purpose of the invention is to simplify the design and increase the broadband. The coaxial splitter contains an input coaxial line, (ON) 1, connected through a matching transformer (ST) 2 to the first output coaxial line 3 and the second coaxial line 4, between the inner conductors 5 of which a ballast resistor 6. CT 2 is made in the form of the first and second wired conductors 7 and 8 located in an ungrounded screen 9. The beginning of conductor 7 and the end of conductor 8 are connected to the inner conductor 10 of the input coaxial line 1, and the end of conductor 7 and the beginning of conductor 8 are connected to the internal odnikam 5 coaxial lines 3 and 4, respectively. The high-frequency power transmitted from ON 1 goes to CT 2 and then spreads between the output coaxial lines 3 and 4. The ballast resistor 6 provides the isolation of lines 3, 4. Electromagnetic coupling between the conductors 7 and 8 increases the coaxial broadband splitter, and structurally CT 2 is made in the form of a segment of a standard two-wire cable. 2 ill.

The invention relates to radio engineering, in particular to power distribution devices between transmission lines.

The purpose of the invention is to simplify the design and increase broadband ™.

In FIG. 1 shows a diagram of a coaxial splitter; in FIG. 2 is the same construction.

The coaxial splitter contains an input coaxial line 1 connected through a matching transformer 2 to the first input coaxial line 3 and a second coaxial line 4, between the inner conductors 5 of which a ballast resistor 6 is connected. The matching transformer 2 is made in the form of the first and second insulated conductors 7 and 8, placed in an ungrounded screen 9. The beginning of conductor 7 and the end of conductor 8 are connected to the inner conductor 10 of the input coaxial line 1, and the end of conductor 7 and the beginning of conductor 8 are connected to the internal nnim coaxial conductors 5, lines 3 and 4 respectively. Contact racks 11 are designed for desoldering conductors.

Coaxial splitter operates as follows.

The high-frequency power propagating from the input coaxial line 1 is supplied to the matching

transformer 2 and then is distributed between coaxial lines 3 and 4. Ballast resistor 6 provides isolation of lines 3 and 4. Electromagnetic coupling between conductors 7 and 8 increases the broadband of the coaxial splitter, and matching transformer 2 is made in the form of a standard length two-wire cable.
