when i use HMC943A, i find the detector voltage of Vref-Vdet is not correct.
i connect the Vref with a 40.2k resistor to Vdd (5V),and i connect the Vdet with a 40.2k resistor to Vdd too.
then i use multimeter to measure the voltage between Vref and Vdet,
i find that when i decrease the input power of the HMC943A，and the output power of HMC943A also become lower.
but the voltage between Vref and Vdet become higher.
the figure below show that the higher the output power ,the higher the voltage
So i don't konw why the test result is not correct?
Look forward for your reply
