We designed a continuously adjustable Bailey splitter/combiner with a sliding mechanism. This device has a good input matching of < -18dB and a low insertion loss of about -0.5dB. 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. We obtained good agreements between predicted and measured transmit field maps with the Bailey splitter/combiner.
