We designed a continuously
adjustable Bailey splitter/combiner with a sliding mechanism. The
sliding mechanism allowed easy handling and precise adjustments. The resistor
free design eliminated the potential safety concern from the previous Ratio
Adjustable Power Splitter circuits.
Figure 1. Diagram of
the power splitter model. The final ratio between P1 and P2
are adjusted by varying the input port’s position (change a and b).
Figure 4. a) Model with daughterboard positioned to have
power splitting ratios indicated below. The red dotted line indicates the splitting
position. Predicted (b) and measured B1+ amplitude maps (c)
with different power split ratios, and the differences between the predicted
and measured maps (d).
