Lumped Element

A possibility of generating ultra-wideband chaotic oscillations in the frequency range up to 60 GHz using a bipolar SiGe heterotransistor is shown. The upper frequency boundary is determined by the cut-off frequency of the active element of the generator. Such a possibility is provided by means of adding a nonlinear circuit into the oscillator layout, in which chaotic oscillations can develop up to the specified frequency. The results of an experimental study of a lumped-element version of the oscillator are presented.

Theoretical Results

The results of integrity of narrowband and wideband lumped element circulators design methodology to the computer aided design system of microwave devices AWR Microwave Office are presented in the article. The calculation method of narrow band circulators circuits which consist of serious and shunt tuning capacities is investigated. The simple and visual method of wideband ferrite isolators optimize design based on circulation impedance calculation is described here. The results of design of the ultra wideband circulator with shunt capacity, serious resonant matching circuit and serious resonant circuit between common terminal and ground are considered. The new theoretical results of calculation of two schematics of wideband high power circulators with serious tuning capacity are presented. The first schematic is formed with matching resonant network being connected in serious at each terminal. It is shown that double hump characteristic is realized. The second schematic is formed with serious resonant network connected between common terminal and the ground. It is shown that four-order Tchebycheff characteristic is realized.
