WebOct 19, 2024 · Around the crossover (~2.2 GHz), the impedance of the shunt resonator tends to increase significantly, while the impedance of the series resonator tends to zero – this creates almost a short between the input and output, while isolating the ground through an almost ideal open circuit. This is the passband behavior.
