Abstract

An equivalent representation of a circuit formed by coupled lines section with cross-symmetrical loads and additional reactive elements is suggested in the form of partial one-port networks with in-phase or antiphase excitation. Analytical relations for the electrical parameters calculation of elements of the circuit, which enables one to implement devices with dual-band operation mode, have been obtained based on the input impedances of these one-port networks. The examples of application of relations obtained for the simulation of dual-band phase shifters with fixed phase difference, impedance transformers and bandpass filters are provided. The simulation results are confirmed by experimental investigations of these devices.
