DELAY LINE
First Claim
1. A delay line including a bandpass filter which has a plurality of resonators between an input terminal and an output terminal, whereinsaid input terminal and one of said resonators which is adjacent to said input terminal are connected to each other by a capacitive coupling or an inductive-coupling;
- said output terminal and one of said resonators which is adjacent to said output terminal are connected to each other by a capacitive coupling or an inductive-coupling;
said resonators are connected to each other by a capacitive coupling and/or an inductive-coupling; and
said couplings comprise at least one capacitive coupling and at least one inductive coupling.

Abstract
In a band-pass filter of a delay line, an input terminal and a first resonator adjacent to the input terminal are coupled through a capacitor. The first resonator and a second resonator adjacent to the first resonator are coupled through a capacitor. The second resonator and a third resonator adjacent to the second resonator are coupled through an inductance. The third resonator and a fourth resonator adjacent to the third resonator are coupled through a capacitor. The fourth resonator and an output terminal adjacent to the fourth resonator are coupled through a capacitor.
