摘要
Abstract
The requirements to up-converter’s indicators such as linear characteristic and spur suppression is very strict, so as not to effect the signal characteristics in the process of up-conversion. The UHF up-converter adopts the dual-conversion scheme to prevent the local oscil ator signals from fal ing in the band. By means of rational al ocation of frequency and level and by use of appropriate electronic devices, the combination interferences resulted by mixing nonlinearity and the output spurs are decreased. The test results show that the scheme is feasible and satisfied with the index requirements.关键词
