Modeling, designing and optimizing microwave stripline elliptic filters with inverters
KUBALOVA A.R., MAXIMOV A.P., TOMASHEVICH S.V., KUBALOV R.I.
The analysis, simulation and optimization of microwave elliptic filter with inverters, implemented in a symmetrical strip line are presented. The electrical characteristics of elliptic BPF with inverters (attenuation, AFC, PFC, VSWR, group delay, etc.) are calculated. The distributions of the electric field in the insulators and current density on the conductors' surface are described.
Key words: elliptic filter, inverter, attenuation characteristic, the amplitude-frequency characteristic (AFC), the phase — frequency characteristic (PFC), group delay, current density, electric field, optimization, quarter-wave transmission line, scattering parameters.
