  • Simulation and experimental study of the in-phase ring power splitter

    A simulation and experimental study of the ring-shaped power divider in the frequency range 2-4 GHz. The simulation was carried out in the application package Microwave Office. The experiment was conducted on a model made on the sheet textolite PT-3 with a thickness of 2 mm. Four frequency dependencies of the transmission coefficient S21 and S31 are given as simulation and experiment results.

  • Experimental research of the intermediate frequency amplifier

    An experimental study of the intermediate frequency amplifier with a bandwidth of 25 to 155 MHz and a gain of about 40 dB was conducted. Given the functional diagram and one cascade of the concept. There is a brief description of the design. The experimental technique is described. The results of the experiment are given: two amplitude-frequency characteristics and one amplitude.

  • Modelling and experimental research of duplexer for a decimeter radio station

    There are represented scheme and design of duplexer for the 300-344 MHz radio station. Simulation of duplexer was implemented in Microwave Office environment. Experimental research was executed on the complex transmission coefficient measuring instrument such as “Obzor-103”. There are shown amplitude-frecuency characteristic of receive and transmission channels. Comparison of the simulations results with natural experiment proving the identical.
