| Abstract: |
| The millimeter wave(MMW) transmission technology for frequency division multipl
exing(FDM) array signals is introduced. For realizing bidirectional transmission
of m
ulti-channel array signals on a wide band MMW circuit link, the tech
nology of frequency division multiplexing and demultiplexing of grouping two fre
quency upconversion spectral assembly is adopted. By the design control and the
correction of phase and amplitude, a good phase and amplitude coherency betwee
n array signals is guaranteed. A prototype with 30-channel array signals transmi
ssion is fabricated and tested. The test results demonstrate the scheme is feas
ible. The technology can be used in the MMW transmission of multi-ch
annel array signals. |
