Barium Tetratitanate MIC Technology

Experimental results on BaTi/sub 4/O/sub 9/ microwave integrated circuit (MIC) characteristics, including microstrip dispersion and loss, have shown excellent agreement with the theoretical predictions. Precision measurements of temperature stability were conducted at 14 GHz. The high dielectric constant (epsilon/sub r/ = 37) and its negative temperature coefficient can be used in specialized MIC's for application to advanced microwave subsystems.
