Abstract:
A variable filter circuit includes a serial arm connected between ports (P1-P2), a parallel arm having a resonator connected in series between ports (P1-P3), and another parallel arm having another resonator connected in series between ports (P2-P3). The serial arm includes an inductor connected between the ports (P1-P2), and the parallel arms include variable capacitances connected in series to the resonators.
