1. A power combiner for a radio frequency, RF, transmitter comprising:
- a first planar figure-8 shaped primary winding configured to support current flow in a figure-8 pattern;
a second planar figure-8 shaped primary winding that with the first planar figure-8 shaped primary winding forms a figure-88 shaped primary winding, the second planar figure-8 shaped primary winding being configured to support current flow in a figure-8 pattern;
a first planar figure-8 shaped secondary winding configured to support current flow in a figure-8 pattern; and
a second planar figure-8 shaped secondary winding that with the first planar figure-8 shaped secondary winding forms a figure-88 shaped secondary winding, the second planar figure-8 shaped secondary winding being configured to support current flow in a figure-8 pattern;
wherein, the figure 8 figure-88 shaped primary winding is substantially overlaid with the figure 8 figure-88 shaped secondary winding.
