Abstract
The signal processing apparatus contains a first signal transforming circuit and a second signal transforming circuit. The first signal transforming circuit includes four first coupled lines and two second coupled lines, wherein two ends of each first coupled line are configured to carry a first pair of differential signals respectively, each second coupled line is magnetically coupled to two of the first coupled lines in parallel and comprises two signal ports, to which the two ends of each of the magnetically-coupled first coupled lines are placed symmetrically for transferring a second pair of differential signals. The second signal transforming circuit is configured to convert between the second pairs of differential signals at the signal ports and a third pair of differential signals at connecting ports of the second signal transforming circuit.
