Abstract
A coupling is provided for coupling non-adjacent resonators of a radio frequency filter. The coupling joins together non-adjacent resonators with a metal strip. The metal strip is physically connected to but electrically isolated from resonators located between the connected non-adjacent resonators. The metal strips include tabs the length of which may be varied. The coupling works with different resonator configurations including horizontally aligned resonators. The coupling allows for the jumping of an even number of resonators can produce zeros at high and low bands. A single coupling of this configuration enables two negative couplings.
