Abstract

An X-band filtering crossover based on ellipsoidal cavities has been designed, fabricated using 3-D printing, measured, and presented. The crossover is designed to have three channels, and each channel exhibits a 3rd-order Chebyshev filtering response. The ellipsoidal cavity with three orthogonal modes (namely TM101x, TM101y, and TM101z) is employed as the crossover junction to achieve the desired cross transmission and channel isolation. To demonstrate the great flexibility of the proposed design, the three channels are designed to have different center frequencies but the same bandwidth. The good agreement between simulation and measurement validates the proposed concept.
