Abstract
A bandpass filter and a method for making a bandpass ladder filter having a center frequency, a first port and a second port. The method has steps of providing a first L network having a first connection, a second connection and an inductive impedance at the center frequency and providing a second L network having a first connection, a second connection and a capacitive impedance at the center frequency. The method further has steps of coupling the first connection of the first L network to the first port, coupling the first connection of the second L network to the second connection of the first L network and coupling the second connection of the second L network to the second port.
