Abstract
This paper describes a new dual mode reciprocal phaser which operates at peak power levels of 100 kW and average power levels of 1500 watts over a -65/spl deg/C to +85/spl deg/C ambient temperature range. The device operates over a 370 frequency band centered at mid S-band. The total phase dispersion for the device is <5/spl deg/ for 200/spl deg/ differential phase shift. Details of the thermal design and ferrimagnetic materials selection are presented. Experimental data are given which indicates that the total insertion phase of the device varies less than 10/spl deg/ when incident average power is varied between 100 and 1100 watts. Little, if any change in differential phase shift is observed over this power range. Other similar phase shifters which provide up to 1000/spl deg/ differential phase shift at lower peak power levels are discussed.Keywords
