摘要
This paper presents a 1024-element Ku-band (10.7-12.7 GHz) polarization agile phased-array SATCOM receiver (RX). The phased array is built on a printed circuit board (PCB) surface-mount low-noise amplifiers (LNAs) and silicon beamformer chips are assembled. The phased-array, with a size of 40×39 cm and a directivity of 34 dB at 11.7 GHz, covers a scan volume of ±70° in all planes, and enables a low-noise operation with a receive G/T 10.5 dB/K at broadside. Its wide angle electronic scanning capability makes it suitable for affordable Ku-band SATCOM ground terminals.
