Abstract : This report describes a new class of ferrimagnetic reciprocal phaser. The phaser is a dual-mode reciprocal type which is capable of operating at high peak and high average power levels. Expressions for insertion phase variations are investigated. Expressions for variation in insertion phase as a function of ambient temperature are derived, as well as equations predicting insertion-phase changes resulting from high average power heating effects. Experimental data for an S-band phaser designed to operate at high peak and high average power levels are presented. A total change in insertion phase of 6.4 degrees for 1,000 watts average input power is computed and measured within experimental accuracy. The merits of this class of phaser for high power application are considered and compared with the nonreciprocal toroidal type. (Author)
