On the Use of Tunable Power Splitter for Simultaneous Wireless Information and Power Transfer Receivers

Figure 16

(a) Measured output power in dBm for both output ports of the tunable PS. While the measurement was taken on one port using the spectrum analyzer, the other port was connected to a 50 Ω wideband load. The horizontal and vertical axes show the varactor diodes’ biasing voltages. (b) Calculated overall loss of the tunable PS for biasing voltage conditions ranging from 0 to 20 V, for both varactor diodes.
