Abstract :
A control method of notch frequencies for coupled-resonator laminated band elimination filter (BEF) is studied. A transmission formula is derived from an equivalent circuit of the BEF. The effectiveness of the method is confirmed by circuit simulation and experiment. The BEF shows good performance of an elliptic function characteristic.
