Abstract

High-performance wideband Bragg cells suited to EW receiver applications were developed using L[111] and S[110] modes in GaP. Efficiency enhancement was demonstrated using a planar phased array design. Demonstrated results include a 1-GHz bandwidth device with a diffraction efficiency of 100% per RF watt. The unified theory of IMPs (intermodulation products) in Bragg cells was applied in the device design. Based on the theory, it is concluded that phased array designs should be used to eliminate IMPs due to nonlinear acoustics.<>
