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.
