2007-10-15 PRIO 205627 / MKA The invention provides an active input matrix balun and a method for the same. The matrix balun has one input transmission line with an RF-in terminal for receiving a single ended RF-in signal and a first output 5 transmission line with a first RF-out terminal and an adjacent second output transmission line with a second RF-out terminal. The invention further provides two balanced RF-out signals at the first and at the second RF-out terminal, where each RF-out signal has an amplitude level equal to or exceeding the amplitude level of the RF-in signal and where the RF-out 10 signals have a mutual phase difference of 1800 and are of equal amplitude levels. Figure 3a to be used. n ryrn c NIZ |
