Two hundred degrees of contiguous relative insertion phase shift (ΔφS21), with insertion losses of 4.6 dB, were measured at room temperature, 14.3 GHz, and maximum dc voltage of 400 V. These results represent significant progress toward viable compact, low-loss, thin-film ferroelectric-based phase shifters at room temperature. © 1999 John Wiley & Sons, Inc.}, year = {1999}, journal = {Microwave and Optical Technology Letters}, volume = {20}, number = {1}, pages = {53-56}, publisher = {John Wiley and Sons Inc.}, issn = {08952477}, doi = {10.1002/(SICI)1098-2760(19990105)20:1<53::AID-MOP15>3.0.CO;2-L}, note = {cited By 33}, language = {eng}, }
