ABSTRACT:
A transformer is provided with four capacitors and four inductors. The first capacitor is electrically connected between a first port and ground in series. The first inductor is electrically connected to the first port in series. The second capacitor is electrically connected between the first inductor and ground in series. The second inductor is electrically connected between the first inductor and the second capacitor in series. The third capacitor is electrically connected between a second port and ground in series. The third inductor is electrically connected to the second port in series. The fourth capacitor is electrically connected between a third port and ground in series. The fourth inductor is electrically connected between the third inductor and the third port in series.
