STUDY AND INVESTIGATION OF THE APPLICATION OF SYNTHETIC MAGNETIC WHISKERS TO MICROWAVE CIRCUITS

Abstract

A feasibility study was performed which showed that ferrite whiskers could be us d to limit X-band power from 0.3 watt to 5 kilowatts with spike energies which do not exceed 50 ergs. The limiter unit is extremely compact and inexpensive to manufacture. Used with a variable reactance diode limiter, the ferrite limiter is capable of protecting receiver diodes in the microwave range. The theory for a very fast variable reactance switch was developed under this contract. The results of analysis showed that an extremely fast (less than 50 nanoseconds) switching action could be obtained with ferrite material. The switch could operate at frequencies greater than 3 kMc with reasonable drive powers. Preliminary analysis of a whisker amplifier indicates that a marked improvement should result in the gain bandwidth product at reasonable pump levels over single crystal YIG types. (Author)
