Design and characterization of SiC varactor-based phase shifters
Paper in proceeding, 2012
Design and realization of two continuously tunable phase shifters for 1.4 GHz band is presented. Both circuits are based on SiC varactors, conceived to enable high-voltage, high-power operation, and suitable for application in the transmitter chain of reconfigurable radios. Experimental characterization shows, for the loaded line phase shifter, 74 ° maximum phase shift with insertion loss lower than 1 dB, and, for the reflective phase shifter, 90 ° maximum phase shift and insertion loss lower than 0.6 dB.
