YSC-7431U / YSC-7431D Up/Down Converter

43 GHz Wideband Frequency Conversion Platform

YSC-7431U and YSC-7431D are wideband RF frequency conversion modules covering 9 kHz to 43 GHz. Together they provide a matched up-conversion and down-conversion platform for high-frequency signal generation, analysis, and subsystem integration.

The converters support external LO input and can be combined with SGR RF transceivers to extend system-level test capability across a broader frequency range. Their low phase noise, strong image rejection, and wide tuning coverage make them well suited to synchronized multi-channel and MIMO-related measurement architectures.
