Ferrite manufacturers for Microwave ferrite devices

Ferrite manufacturers for Microwave ferrite devices

Ferrite manufacturers for Microwave ferrite devices

Can someone recommend a commercial manufacturer of Ferrite rods and rectangles for use in microwave devices at frequencies in the 2-500 Mhz range.

I'm trying to make a low frequency ferrite loaded antenna, hence references on low frequency ferrite loaded antennas in the 2-100 mhz range would be appreciate too.

could someone also give me some tutoring on using ferrites


RE: Ferrite manufacturers for Microwave ferrite devices

I don't think you can get one to work much over 10 MHz due to ferrite losses, but am not sure.

Basically you take a ferrite rod, wrap some wire around it making a big inductor.  You then resonate it with a series variable capacitor.  You wrap a smaller coil around the rod to couple energy out of the resonator.  

The antenna will pick up signals at the frequency where the L-C circuit is tuned to resonate.  It is fairly directional, like a dipole antenna.  Also, it is fairly narrow band.
