Neste artigo, propomos um método de projeto de filtro anti-aliasing de radiofrequência (RF) considerando o efeito de uma característica de roll-off em uma figura de ruído (NF) no receptor de subamostragem de RF direto. O método proposto é útil para recepção de banda larga em que a largura de banda do sistema (BW) tem quase metade da frequência de amostragem (1/2 fs). Quando o BW do sistema é estendido quase 1/2 fs, a banda roll-off está fora da zona desejada de Nyquist e afeta adicionalmente o NF. O método proposto oferece uma meta de projeto em relação à característica de roll-off e não apenas à taxa de rejeição. A meta é útil como guia de design para atender à NF permitida. Projetamos o filtro com base no método proposto e ele é aplicado ao receptor de bordo com subamostragem direta de RF para satélite de alto rendimento (HTS) de banda Ka. O valor NF medido do receptor implementado quase correspondeu ao valor projetado. Além disso, o receptor atingiu a largura de banda de recepção que é 90% de 1/2 fs.

Abstract: In this paper, we propose a radio frequency (RF) anti-aliasing filter design method considering the effect of a roll-off characteristic on a noise figure (NF) in the direct RF undersampling receiver. The proposed method is useful for broadband reception that a system bandwidth (BW) has nearly half of the sampling frequency (1/2 fs). When the system BW is extended nearly 1/2 fs, the roll-off band is out of the desired Nyquist zone and it affects NF additionally. The proposed method offers a design target regarding the roll-off characteristic not only the rejection ratio. The target is helpful as a design guide to meet the allowed NF. We design the filter based on the proposed method and it is applied to the direct RF undersampling on-board receiver for Ka-band high throughput satellite (HTS). The measured NF value of the implemented receiver almost matched the designed value. Moreover, the receiver achieved the reception bandwidth which is 90% of 1/2 fs.
