(actually a TNO design but shown here for completeness)
F1c2=F1c with a redesigned frontpanel for better mechanical stability
Can be used to upconvert or downconvert a signal to/from the 4-8GHz band by connecting a microwave source set at the required frequency to the LO input
F1c datasheet
This module is using a chip from Analog devices/ Hittite: HMC525LC4
Specifications can be also derived from the datasheet of this chip
No supply is needed, no remote interface present
