A circuit (100, 800) for combining/splitting first and second RF signals having different wavelengths of x and y, respectively, the circuit comprising: (a) first and second transmission portions (101, 102) coupled at an intersection (103), the first transmission portion (101) comprising at least two intersecting transmission lines (104, 105), each having a length which is an odd multiple of about 1A y, the second transmission portion (102) comprising at least two intersecting transmission lines (106, 107), each having a length which is an odd multiple of about 1/4 x; and (b) first, second and third ports (108, 109, 110), the first port (108) located at the first transmission portion (101), the second port (109) located at the intersection (103) of the first and second transmission portions (101, 102), and the third port (110) being located at the second transmission portion (102), the first and second ports(108, 109) being electrically coupled, and the second and third ports (109, 1 10) being electrically coupled. |
