Super High-Selectivity Fifth-Order Bandpass Filter with Twelve Transmission Zeros [PDF]

open access: yesRadioengineering, 2018
A fifth-order bandpass filter (BPF) with super high selectivity using three pairs of coupled lines and two open stubs is proposed. Twelve transmission zeros (TZs) from 0 to 2f_0 (f_0 denotes center frequency of the passband) and five transmission poles ...

Quality factor of a transmission line coupled coplanar waveguide resonator

open access: yesEPJ Quantum Technology, 2018
We investigate analytically the coupling of a coplanar waveguide resonator to a coplanar waveguide feedline. Using a conformal mapping technique we obtain an expression for the characteristic mode impedances and coupling coefficients of an asymmetric ...
