Description

Fig.:: [0001] The invention relates to radio engineering, in particular, to broadband devices combining the power of two generators with symmetry and relatively common bus outputs whose powers differ by a factor of three or to broadband power dividers in a ratio of 1: 3. A wideband device for combining unequal powers of oscillators of electrical oscillations is known, which contains two multi-wire lines, two loads, two generators with an asymmetrical output and powers that differ by half RZ. However, when using such a device to add powers that differ by three times, losses occur the expense of power in the breaking load, and for balancing the power of generators with symmetrical outputs, additional symmetrical transformers are needed. In this case, the device is difficult and has a low CGD. Closest to the invention is a device for combining unequal powers of electrical oscillators, comprising a series-connected first generator, first, second and third conductors, a first load, fourth-fifth and sixth conductors, and a second generator connected between the beginning of the third conductor and the end of the fourth conductor, and a second load connected between the beginning of the second conductor and the end of the fifth wire $ scale. The device provides the addition of the power of generators with satellite outputs, the power of which is three times different 2, However, the known device has a relatively narrow range of operating frequencies, due to the influence of the conductor scattering inductance and their capacitance. The purpose of the invention is to expand the operating frequency range. The goal is achieved by the fact that in a system of adding unequal powers of electric oscillator generators containing the first generator, the first, second and third conductors connected in series, the first load, the fourth, fifth and sixth conductors, and the second generator connected between the beginning of the third conductor and the end of the fourth conductor, and the second load connected between the beginning of the second conductor and the end of the fifth conductor, between the beginning of the first conductor and the end of the fourth conductor, a third load is included ka, between the start of the third conductor and the sixth conductor end including the fourth load, the first, third and fifth conductors are grouped together, forming the first three-wire line, and the second, fourth and sixth wires are combined in another group, forming a second three-wire line. FIG. Figure 1 shows the circuit diagram of the device using three-wire strip lines; in fig. 2 - the same, when using segments of coaxial lines. The device contains conductors 1-6, the first 7 and second 8 generators, loads 9-12, while the group of conductors 1, 3 and 5 forms the first three-wire line 13, and the group of conductors 2, 4 and 6 - the second three-wire line 14. Beginning of conductors marked by dots. For the embodiment of the device of FIG. 2 | CI 1 and 5 are the central conductors of the coaxial line segments, the outer conductors of which, connected at the beginning and at the end, form the CONDUCTOR 3, the conductors 2 and 6 are also the central conductors of the coaxial line segments, the outer conductors of which, connect (( At the beginning and at the end, they form a conductor 4. The device (Fig. 2) works as follows: If the characteristic impedances of all segments of coaxial lines with conductors 1, 2, 5 and 6 and loads 9-12 are equal to each other and pasHid R, and the load resistance to is equal to R / 3, then the generators 7 and 8 are matched in a wide frequency band and are interconnected, with the load for generator 8 equal to R / 3 and for generator 7 to R. The condition of synphase and equality of amplitudes of the output voltages of generators 7 and 8 (in according to the arrows) the voltage at loads 11 and 12 is absent, i.e. the device can be excluded, and at the same time the inputs of all segments of coaxial lines

oscillations of the same amplitude and the corresponding phase are received so that at the outputs of the sections of coaxial lines the oscillations mutually compensate for the load 10 and add up for the load 9. The loads 11 and 12 are necessary to ensure uncoupling between the generators. For example, when the generator 8 is short-circuited, the load for iBHepaTopa 7, due to the connection of loads 11 and 12 and the series-connected inputs of the coaxial lines with the central conductors 1 and 6, remains equal to R..

The matching mode in sections of coaxial or flat lines allows the working range to be expanded to the top, and the possibility

Increasing the length of the segments — when placed inside the magnetic core — allows the working range to be extended to the low frequency range.

This device is also a wide-band power divider. If instead of the generator 8 to connect the ballast load of R / 3, then MODtHocTb generator 7

divided between, loads 9 and 10 in the ratio 1: 3.

Thus, in this device, by using sections of coaxial or flat three-wire lines, additional loads and corresponding connections between conductors, the generators are matched and the working frequency range is expanded.
