Abstract

The work is devoted to the development and research of a three-channel decimeter range power divider. Power dividers are widely used in all branches of radio electronics and wireless communication systems, in particular in radio communication systems, radio monitoring systems and others. At the first stage of research, a three-channel divider was calculated based on the Wilkinson scheme, implemented on quarter-wave line sections. To minimize losses in the divider, air-filled coaxial line sections were used for its implementation. The ballast resistance system is implemented according to the triangle scheme, which made it possible to minimize its parasitic inductance. The expansion of the operating frequency band is achieved by using a two-stage scheme with an additional quarter-wave line section. At the second stage of the research, the parameters of the developed divider were simulated in the Micro-Cap 12 program, which is currently freely available. For this purpose, the serial parameters of all line sections of the divider were calculated. The simulation showed that in the range from 350 MHz to 550 MHz, the isolation between the channels is no worse than -23.2 dB, and at the central frequency – no worse than -40 dB. At the third stage, a research of the implemented experimental prototype of the three-channel divider was carried out. As the research showed, the transmission coefficient from the input to any of the output channels of the divider in the entire operating frequency band is no worse than -4.8 dB, and the reflection coefficient from the input is no worse than -20 dB, which indicates its high efficiency. The isolation between the channels at the boundary of the operating range is no worse than -22 dB and is heading to -40 dB in its central part. The results of the experimental research coincide well with the modeling results in the Micro-Cap 12 program, which confirms the reliability of the numerical calculation and the correct choice of the divider model.
