As the HMC8192 is IQ passive mixer, is it a tru reciprocal device on all ports? I would like to use as frequency shifter . My input would be the LO port, I plan to drive the IF with a "quadrature DDS" and the output would be the RF port. I am expecting that the I/Q DDS inputs would do the "switching". If the input (LO port) is 35.0000 GHz and I set DDS to 10KHz I would expect an output of 35.000010 GHz or 34.99999 GHz depending on the I/Q quadrature of the DDS ( IF Inputs). In this application the IF input id the "LO" input and associated drive level. What would be the best performance data to look at on the data sheet.
