摘要: A mobile satellite payload 18 and a method for sampling communication signals 26 are provided. The uses plurality of receive radiating elements 24 within phase array antenna 22 to convert the received [S(t)]. low noise amplifiers (LNAs) 28 amplify [S(t)] then be by analog-to-digital (A/D) converters 29 . A/D transform into digital baseband [ S ″(t)].
