DEVELOPMENT OF A FERRITE MATERIAL FOR A HIGH POWER PHASE SHIFTER AT S-BAND

Abstract

The development of a ferrite material suitable for operation at 250 Kw peak power in a phase shifter device operating at S-band frequencies is discussed. This work is centered around the nickel aluminum gallium ferrite system. Several compositions were prepared and fired and an evaluation was started. A preparation procedure was developed and a variation of this procedure will be used for the composition selected for device use. The hot press and flame spray apparatus was designed. All the required measuring setups were assembled except the loss vs. peak power apparatus. The static properties of the ferrites, saturation magnetization as a function of temperature, Curie temperature, density, dielectric constant and dielectric loss were measured and are discussed.
