RAJAPKV RTP SLOT The two output ports have a 90° phase difference (-i to −1) and so this is a 90° hybrid. For example, the isolation between ports 1 and 4 can be 30 dB while the isolation between ports 2 and 3 can be a different value such as 25 dB. Domestic broadband internet service can be provided by cable TV companies (cable internet). The hybrid ring discussed above can also be implemented in waveguide. With port 1 or port 3 as the input the hybrid ring is a 0° hybrid as stated. It will cross over the inputs to the diagonally opposite outputs with a phase delay of 90° in both lines. The phases of the inputs to each power combiner are arranged such that the two inputs are 90° out of phase with each other.|Yeh Hai Mohabbatein
