the RF(Radio Frequency) channel based on microwave technology features limited bandwidth
limited working frequency
limited multi-frequency conversion capability and poor versatility
which seriously prevent the high-throughput satellites from the large spectrum coverage and the multi-channel conversion capability of large bandwidth. To solve this problem
based on the comparative analysis of the research status of microwave photonic RF channel
this paper proposes a broadband cross-band microwave photonic RF channel implementation method based on parallel architecture
and the corresponding simulation analysis and experimental verification are carried out. The test results show that the down conversion input frequency of the RF channel can cover 27GHz~52GHz
and the output frequency can cover 17GHz~24GHz; the up conversion input frequency can cover 25GHz~27GHz
and the output frequency can cover 37GHz~43GHz. The bandwidth is larger than 2GHz
the in-band flatness is lower than 3dB
the conversion gain is lower than -10dB
and the spurious free dynamic range (SFDR) is higher than 100dB·Hz
