Abstract

Hughes has recently developed a broadband low-sidelobe active array that uses T/R modules of a common-leg architecture and parts from multiple suppliers for each MMIC chip. Design of an 1140 element (8 watts per element), 4 GHz, rms sidelobes (<43 dB), X-band active array is described. High-precision phase and amplitude control (PAC) modules on each row of elements enables independent aperture illumination for receive (sum, delta-azimuth, delta-elevation) and transmit-sum channels.
