Hi all,

I am a r&d engineer in a company for analytical devices in magnetic resonance equipment. For one of our recent projects we have to design a dielectric resonator with a very low resonant frequency (700MHz ... 1GHz). This is not a big problem as long as you have the right dielectric, and this is my problem. Due to the setup and the environment of the resonator in the application the dielectric material must have the following material parameters:

eps_r >= 400
Q@1GHz >= 200 (although low, this is enough for me)

thermal behaviour:
df <= 100ppm/degC
mue_r = 1 (must be absolutely non-magnetic)

Here is the question: Does anybody know where I could get such a material from? Are there any publications about such materials?
