Abstract
Monolithic Ka-band phase shifter circuit that employs voltage tunable BaSrTiO3 (BST) parallel plate capacitors is presented here. The circuit is capable of continuous 0°-157° phase shift at 30 GHz with an insertion loss of only 5.8 dB and return loss better than 12 dB. In addition to promising loss performance (27.1°/dB) at 30 GHz, the circuit reported here has several advantages over previously reported BST phase shifters such as moderate control voltages (20 V), room temperature operation, and compatibility with monolithic fabrication techniques
