Abstract :
In this paper a 90deg variable phase shifter operating at 2.3 GHz is presented. This circuit uses a combination of variable gain amplifiers and an analog summation circuit to to control the magnitude of each vector and sum them together. Experimental results show a 93.7deg variable phase shift range while maintaining a 0.08 dB amplitude error. The insertion loss is -4 dB and the input and output reflection are -22.6 dB and -10 dB. The device measures 0.20 mm2 without bonding pads.
