摘要：

We report on recent developments in microwave applications and understanding of thin Ba50Sr50TiO3 films. Most of our recent efforts have focused oil developing low loss, wide band phase shifters from X-band (8.4 GHz) to Ka-Band (26.5 GHz) for scanning reflectarray antennas. Attempts to reduce tan delta by Mn-doping Ba50Sr50TiO3 films are briefly discussed. We have demonstrated a hybrid device at X-band that produces in excess of 300 degrees of phase shift with about 3.5 dB insertion loss and greater that 10% bandwidth. Preliminary results are presented here. The effects of mild (600 rad Si) proton radiation on device performance will also be discussed. Preliminary results oil optical phase shifters will be included.
