Ferroelectric
materials based on BST (barium strontium titanate) could be used as the basis
for new advanced-technology microwave and particle accelerator devices. In
particular, the electronic properties of this material allow one to create an
X-band high-power radio frequency (rf) switch with sufficient peak power for use
in linear collider rf systems. This
project will develop a new BST material with a permittivity of ~500 and a loss
factor of 1×10-3 at 11.4 GHz. In
addition, a process for sintering and forming large sized objects (required for
phase shifter components) made of BST ceramic will be demonstrated.
In Phase I, a BST-based bulk ferroelectric with permittivity of 400-500,
loss factor of (3-4)´10-3 at 11.4GHz, and
tunability of 15-20% at 5 V/mm
bias field will be developed. The
phase composition and structure of the BST samples will be studied as a function
of the solid-solution composition, raw materials, and synthesis techniques. The
dielectric response of the material in the (3-12) GHz and 35 GHz frequency
ranges will be demonstrated.
Commercial
Applications and Other Benefits as described by the awardee:
The ferroelectric-based tunable device technology should have application
to a variety of other high-frequency, large-signal devices. Tunable
devices made using bulk and thin-film ferroelectric technology also have many
potential applications for the military and wireless communication industries.
