Patent ID: 8008990

Claim:
A P-channel multiplexer, comprising P rows of sequentially coupled resonators, where P is an integer and P≧2, the i-th row of said P rows comprising n i of said sequentially coupled resonators different from the resonators of each other row of said P rows, where n i is an integer greater than or equal to 2, and i is an integer between 1 and P inclusive; a common terminal in communication with first resonators of k of said rows of sequentially coupled resonators, where k is an integer less than P; P channel terminals, each of them in communication with each respective last resonator of each respective row of said P rows, and at least one coupling which connects at least one resonator of any j-th row of said P rows and at least a resonator of the (j+1)-th row of said P rows, j belonging to j=1, . . . P-1.
